  • Air Sampling Instruments For Radiological Emergency Preparedness

    The necessity of state-of-the-art air sampling and airflow calibration instruments for radiological emergency preparedness teams (REP), civil survey teams (CST) and radiological assistance program teams (RAP) is clearly established in today’s terrorism sensitive environment.Instruments need to be lightweight, reasonably small, simple to operate and to display accurate measurement values that are ...

  • The Fundamentals of the Air Sampler Calibration-Verification Process

    INTRODUCTION The calibration of an air sampling instrument using a reference air flow calibrator requires attention to scientific detail in order to establish that the instrument’s reported values are correctly stated and valid under the actual operating conditions of the air sampling instrument. DEFINITIONS For the purposes of this ...

  • Pure water pH measurement in low conductivity samples

    Normally, pH measurements are made in water with 1,000 to 10,000 uS/cm conductivity. The conductivity conies from dissolved solids, typically, salts plus net acid or base which explains the exhibited pH. These dissolved substances are in the solution in ion form, which makes such solutions conducting. With 1,000 uS/cm conductivity of mobile ions pH electrodes have a good circuit and give fast, ...

  • Calibration and Spectrum Troubleshooting: IMS Spectrum Introduction, Measurement and Calibration (Series Part 1 of 4)

    Introduction The AirSentry II AMC Analyzer detects airborne molecular contamination (AMCs) in cleanroom manufacturing environments. AMCs cause defect loss and product degradation and its reduction is critical for manufacturers to stay competitive. AMC measurement techniques must allow for accurate, reliable event detection in real-time. The AirSentry II analyzer uses Ion Mobility ...

  • Gas Analyser Unit

    Gas Analysers are used in several industries, chemical industries in particualr use gas analysers to monitor their gas emission levels, air quality samples are compared to high purity reference gases to analyse and measure the emissions.  A common practice is to “calibrate” the sample air against clean, dry pure reference gases such as H2, He, Ar, or N2. The ...
