Setting up a Low Flow Sampling Train - Adeel Hassan, Technical Product Manager at Casella
High chemical concentrations can pose an immediate risk to life but repeated exposure to relatively low concentrations can lead to long term (chronic) illnesses, cancers and even hearing loss in the case of ototoxic chemicals such as nitriles, metals and their compounds and solvents.
In the particular case of solvents, personal monitoring using a low flow pump and an adsorbent tube is a preferred solution, whereby a time weighted average concentration may be determined by drawing a known volume of air through the tube at constant flow over an entire shift. The tube is then desorbed and subsequently analysed by a competent laboratory.
Choice of Pump
It is advisable to use a dedicated low flow, (Read More)
