Used GOW-MAC 21-250 #9239865 for sale

GOW-MAC 21-250 is a residual gas analyzer (RGA) used to detect, identify, and quantify volatile organic compounds (VOCs). It is designed to provide fast, accurate, and reliable measurement of residual gases in a closed system. 21-250 is based on ion mobility spectrometry (IMS) technology, which utilizes an ion beam for the identification and quantification of low concentrations of substances. The IMS principle uses high voltage electrodes to form an ionization space between two plates. This space is charged with a gas or air sample and then the sample is filtered through an ion filter. The detected ions are dissolved in a mobile electrolyte solution and then amplified. This amplification process produces a signal which can then be registered by GOW-MAC 21-250. 21-250 can detect VOCs down to a level of 1 ppb or part per billion. By using a flexible and programmable field of view, GOW-MAC 21-250 can be used to measure a variety of compounds. It offers selectable scan rates to optimize speed and accuracy of measurements. The instrument also offers a variety of selectable resolution settings and a digital display indicating the concentration levels of the compounds being measured. Additionally, 21-250 has an auto-ranging facility for increased accuracy and can store measurement data and settings to ensure repeatable analysis. Furthermore, it has a built-in printer to provide hard copies of results. GOW-MAC 21-250 is often used in safety related applications in semiconductor and pharmaceutical production, food production, cleanroom maintenance, and atmospheric pollution monitoring. Overall, 21-250 offers an efficient and reliable way to measure low-concentrations of VOCs. Its flexibility, range, accuracy, and selectable scan rates make it an ideal choice for a variety of applications.
