Introducing the Model 714 NO2/NO/O3 Calibration Source
In December 2018 we introduced another newcomer to our product line, the Model 714 NO2/NO/O3 Calibration Source™. It combines our Model 408 Nitric Oxide Calibration Source™ with our Model 306 Ozone Calibration Source™ to provide a highly portable transfer standard for three pollutant gases without the need for a compressed gas cylinder of nitric oxide. Calibrated concentrations of O3 are produced by photolysis of oxygen, and calibrated concentrations of NO are produced by photolysis of nitrous oxide. In addition, calibrated concentrations of NO2 are produced by gas-phase titration of NO with O3. Calibrations sequences can be programmed in internal memory via a user-friendly touch screen interface. More Info

Introducing the Black Carbon Photometer
In December 2018, 2B Tech launched the newest member of its lineup, the Black Carbon Photometer™ (BCP). The BCP is a rugged, portable, highly accurate and economical instrument for the direct measurement of atmospheric black carbon particulates in polluted urban environments, without the need for preconcentration. The BCP uses the simple and direct technique of long-path photometry at two wavelengths (405 nm and 880 nm) to quantify—in real time—the total extinction and mass concentrations of particulates in the aerosol (gas + particle) phase. The Black Carbon Photometer is useful for researchers studying the role of black carbon in air quality and climate, and for air quality managers interested in estimating community exposure risks.

New FEM for NO2
Our Model 405 nm NO2/NO/NOx Monitor has been designated as a Federal Equivalent Method for NO2 (EQNA-0217-243). In the Model 405 nm, the NO2 is measured directly by absorbance at 405 nm, analogous to an ozone monitor. This approach distinguishes the Model 405 nm from chemiluminescence-based instruments, in which NO2 must be converted to NO using either a molybdenum or photolytic converter with highly variable efficiency. The wavelength of 405 nm was chosen because no other species found in ambient air has significant absorbance at that wavelength, making the Model 405 nm extremely selective for NO2. The versatile Model 405 nm also measures NO and NOx (NO by conversion to NO2 using ozone, and NOx is determined as the sum of NO2 plus NO). More info

2B Tech's DewLine™:
An Innovation that Eliminates Water Vapor Interferences A new video shows how 2B Tech's DewLine™ eliminates water vapor interferences in ozone measurements. In a side-by-side comparison, a 2B Tech ozone monitor and a monitor that does not use a DewLine™ are exposed to conditions of rapidly changing humidity but unchanging ozone. All commercially available ozone monitors based on UV absorbance exhibit a water vapor interference. Most scientists who work with UV ozone instruments are aware that rapid changes in humidity, as may occur during a frontal passage, will cause a large zero shift that may last for several hours. This interference is especially troublesome in balloon and aircraft measurements where the instrument may rapidly pass through alternating dry and humid air parcels. It also is a problem when one calibrates an ozone instrument using extremely dry tank air. 2B Technologies developed a method to use a Nafion® tube to equilibrate humidity during I and Io measurement cycles, thereby completely eliminating the water vapor interference -- even for step changes between 0 and 90% RH. Nafion® tubes of the appropriate length and internal diameter and modified to easily attach to 2B Tech detection cells are available under our trademark name DewLine™. All new instruments are provided with DewLines™. We recommend installation of a DewLine™ on all instruments returned for service if they do not have one. Ozone monitors manufactured by other companies benefit from the use of the DewLine™ as well. |

2B Tech's Aqueous Ozone Monitor Awarded a U.S. Patent
In Fall of 2016, our Model UV-106-W Aqueous Ozone Monitor was awarded a U.S. patent. The Monitor uses MicroSparge™ technology to make interference-free measurements of dissolved ozone in clean or "dirty" water with high precision and accuracy. Unlike most dissolved ozone sensors, the Model UV-106-W does not use a membrane, which can become contaminated over time. Instead, the Monitor works by stripping the dissolved ozone in a ~2 mL sample from solution, and then measuring the ozone in the gas phase using a UV absorbance method (see animation here). Because dissolved interferences are left behind in the solution, the Model UV-106-W can be used to measure ozone in “dirty” water, such as drinking water, which can contain a wide variety of dissolved inorganic and organic impurities and suspended particles. It offers a precision and accuracy of 0.05 ppm or 1% of reading, a new measurement every 10 seconds, multiple averaging times, LED alarms, and a NEMA waterproof housing. |

Personal Ozone Monitor Certified by the US EPA as a
Federal Equivalent Method (FEM) Upon publication in the Federal Register on 26 August 2015, the Personal Ozone Monitor became the smallest Federal Equivalent Method (FEM) ever approved for an air pollutant. The POM has dimensions of 4 x 3 x 1.5 inches and weighs only 0.75 lb (340 g). It has a built in GPS so that ozone measurements may be logged continuously along with geographic location. By folding the optical path in the shape of a "U", it was possible to achieve approximately the same path length in the POM as in the Models 202, 205 and 106-L and thus have similar precision and accuracy (~2 ppb). For more details see: POM |

Models 106-L and OEM-106-L Ozone Monitors™ Certified as a
Federal Equivalent Methods (FEM) Upon publication in the Federal Register on 4 November 2014, the Model 106-L and Model OEM-106-L Ozone Monitors officially became Federal Equivalent Methods (FEMs). As designated FEMs, our Models 106-L, 202, 205 and 211 Ozone Monitors may be used by states and other monitoring agencies under 40 CFR Part 58, Ambient Air Quality Surveillance, for monitoring for compliance with the Clean Air Act. The Model 106 series was designed as an "Ozone Monitor on a Board" in order to both reduce manufacturing cost and enhance reliability by eliminating nearly all wiring connections. An internal long-life pump is standard on the Model 106-L. The Model 106-L is our least expensive ozone monitor and is already widely used for health and safety monitoring in industrial ozone applications. It also serves as the ozone monitor in our educational outreach program, the GO3 Project. A description of the Model 106 series of ozone monitors, which includes medium (0-1000 ppm) and high concentration (0-20 wt%) instruments is provided here. |

Launch of Model UV-106-W Aqueous Ozone Monitor™
The Model UV-106-W Aqueous Ozone Monitor™ was launched at the International Ozone Association (IOA) meeting in Montreal, Canada, in August 2014. This new instrument uses our patent-pending MicroSparge™ technology to measure dissolved ozone in water with high precision and accuracy. Unlike most dissolved ozone sensors, the instrument does not make use of a membrane that will foul over time. Instead, dissolved ozone is measured by nearly complete sparging of ~2 mL of water and integrating the gas-phase concentration of the ozone stripped from solution. Because ozone is measured in the gas phase, interferences from particles and dissolved inorganic and organic compounds are removed, making the instrument applicable to both ultra pure water and "dirty" water, such as drinking water. A description of the new Aqueous Ozone Monitor is provided here. |

Launch of Model 405 nm NO2/NO/NOx Monitor™
The Model 405 nm provides a direct measurement of nitrogen dioxide (NO2) by absorbance of light at 405 nm with a precision of 2 ppb or better. The high precision is achieved by using a White cell with a path length of ~2 m. Other methods such as chemiluminescence require conversion of NO2 to nitric oxide (NO) using a molybdenum or photolytic converter to measure NOx (NOx is defined as NO + NO2) and then determine NO2 as the difference between NOx and NO. Such methods suffer from inaccuracy due to variations in conversion efficiency and interferences from other compounds that may convert to NO. The Model 405 nm also measures NO by modulating the addition of ozone with ~100% conversion of NO to NO2. NOx is then determined by simply adding NO and NO2. A description of the NO2/NO/NOx Monitor is provided here. |

Model 211 Scrubberless Ozone Monitor™ Certified as a
Federal Equivalent Method (FEM) Designation of the Model 211 Ozone Monitor as a Federal Equivalent Method (FEM) was published in the Federal Register on 18 June 2014. As a designated FEM, the Model 211 Ozone Monitor may be used by states and other monitoring agencies under 40 CFR Part 58, Ambient Air Quality Surveillance, for monitoring for compliance with the U.S. Clean Air Act. The Model 211 replaces the traditional solid phase ozone scrubber with a titration of ozone using nitric oxide gas generated on-line in the photolysis of nitrous oxide (N2O). The N2O may be supplied from Whippit cartridges (used for producing whipped cream) for portable applications. Because of its lack of interference from other UV-absorbing species such as aromatic compounds and mercury vapor, the Model 211 provides a more accurate measurement of ozone. For the past two years the Model 211 has been undergoing testing by the EPA for evaluation as a possible new Federal Reference Method (FRM) as well. A description of the NO2/NO/NOx Monitor is provided here. |

Launch of GPT Scrubberless Module™
The GPT Scrubberless Module™ allows you to convert conventional ozone monitors, such as the Teledyne-API Model 400E, to our new gas phase titration (GPT) technology (US Patent # 8,395,776 B2). This "scrubberless" module replaces the traditional solid-phase scrubber and removes interferences from mercury, aromatic VOCs and other UV-absorbing compounds. On high ozone days in highly polluted cities, such interferences can contribute up to a few ppb of false ozone reading. In many cases, a region can be out of compliance with the ozone standard due to measurement errors caused by the use of solid-phase scrubbers. The GPT Module replaces the scrubber in your conventional ozone monitor with a source of nitric oxide (produced online by photolysis of N2O) to selectively destroy ozone during the reference measurement cycle, thus eliminating interferences from Hg and UV-absorbing compounds since these species are not modulated by the gas-phase scrubber. A description of the GPT Module is provided here. |

Flow Through Ozone Monitor
As of 1 August 2011, the Models 106-L and 106-M Ozone Monitors are available in a "Flow Through" configuration. This optional configuration allows the sampled air stream to continuously pass through the instrument so that the ozone concentration is not perturbed by the measurement and the ozone can still be used in the process being monitored. The Flow Through ozone monitors are simply placed inline with the experiment or process. Ozone-scrubbed air for the reference measurement is produced from ambient air using an internal air pump and ozone scrubber. For more details see: Flow-Through Ozone Monitor |
