[Audio] photoionization detectors (PIDs) and their functionality.

[Audio] The third slide of the UltraRAE 3000 training presentation focuses on the use of Photoionization Detectors, or PIDs. These detectors are crucial for the instrument, allowing for real-time measurement of organic and inorganic vapor concentrations in low levels, ranging from parts-per-billion to 10000 parts-per-million. The PID works by using an ultraviolet (UV) lamp to ionize molecules, causing them to release an electron and form a positive ion. This occurs when the Ionization Potential (IP) of the molecule is less than the output of the UV lamp, which can range from 9.8 electron volts (eV) to 11.8 eV. The resulting ions are then guided and collected, with the ion current amplified and converted into a digital meter readout, giving us the concentration of the compound in parts-per-million. The most commonly used UV lamps for field work are the 9.8 eV, 10.6 eV, 11.7 eV, and 11.8 eV lamps. It's important to note that these lamps can have varying lifespans, with the 10.6 eV lamp lasting around 3000 hours, the 11.7 eV lamp lasting around 200 hours, and the 11.8 eV lamp lasting around 500 hours. However, the actual lifespan will depend on proper use and maintenance. To conclude, PIDs are essential for accurate measurements with the UltraRAE 3000, utilizing UV lamps to create ions and provide precise readings in parts-per-million. Knowing the features and limitations of PIDs is important for their effective use in the field. This concludes the overview of PIDs, and the next slide will cover the various applications of the UltraRAE 3000..

[Audio] Slide number 4 discusses the largest group of compounds that can be measured by a PID, or photoionization detector, which are known as organics. These compounds contain carbon atoms and include aromatic compounds like benzene, toluene, ethyl benzene, and xylene. Other types of compounds in this category include ketones and aldehydes, which have a C=O bond, such as acetone, methyl ethyl ketone, and acetaldehyde. Amines and amides, which are carbon compounds containing nitrogen, such as diethylamine, are also included. Additionally, chlorinated hydrocarbons like trichloroethylene and perchloroethylene, sulfur compounds like mercaptans and sulfides, unsaturated hydrocarbons like butadiene and isobutylene, alcohols like isopropanol and ethanol, and saturated hydrocarbons like butane and octane can also be measured using a PID. PIDs can also be used to measure some inorganics, which do not contain carbon. These include compounds like ammonia, certain semiconductor gases like arsine and phosphine, as well as hydrogen sulfide, nitric oxide, and bromine and iodine. With this understanding of the range of compounds that can be measured by a PID, we will continue our training on the UltraRAE 3000 instrument..

[Audio] Slide number five discusses the importance of understanding PID Correction Factors. The Correction Factor, also known as CF, measures the sensitivity of a PID to a specific gas and is only relevant when using an instrument calibrated for one compound while sampling for another. To determine the sensitivity, the relationship between the calibration gas and the alternative compound is considered, giving the Correction Factor. An Isobutylene-calibrated instrument will show a higher reading when sampling for toluene due to the difference in the PID's response to toluene compared to Isobutylene, as shown in the response/correction factor. For example, toluene has a correction factor of 0.5, meaning that if the instrument reads 100 ppm, the correct value for toluene would be 100 ppm multiplied by 0.5, which is 50 ppm. Most manufacturers have published lists of response/correction factors for various compounds, which are now commonly integrated into PIDs for easy correction of readings. Here are a few examples of correction factors for common compounds: Acetone - 0.7, Ammonia - 8.5, Benzene - 0.5, Butadiene - 0.85, Diesel Fuel - 0.75, Ethanol - 8.7, Gasoline - 1.1, n-Hexane - 3.3, Styrene - 0.45, Toluene - 0.51, Vinyl Chloride - 2.2, and Xylene - 0.43. Understanding PID Correction Factors is crucial for accurately interpreting instrument readings, and we will delve into this in further detail in the following slides..

[Audio] We will be discussing the example correction factors for the UltraRAE 3000 instrument. The list includes various compounds and their corresponding correction factors, which are used to adjust the readings on the screen to accurately reflect the actual concentration of the compound in the air. For example, Acetone has a correction factor of 0.7, meaning that if the instrument detects a concentration of 1 ppm, the reading on the screen will be adjusted to 0.7 ppm. Some correction factors may be greater than 1, resulting in a lower reading on the screen compared to the actual concentration of the compound in the air. It is important to consider these factors when interpreting the results from the UltraRAE 3000 instrument. Understanding the correction factors for each compound is essential. In summary, we have discussed the example correction factors for the UltraRAE 3000 instrument and their role in accurately reflecting the concentration of compounds in the air.
