Measure alcohols using the most recent method (OSHA 5001), published in 2021.  The price includes the vapor sampler, return shipping, analysis, and final report.  The method uses the familiar solvent carbon disulfide as the desorber (remember OSHA 7) but combined with dimethylformamide (DMF).  The purpose of the added DMF is to dissolve water that's co-adsorbed with the alcohols in the adsorbent. With carbon disulfide only as the desorber, the alcohols appear to be partitioned between two phases, one in the desorber and the other in absorbed water that’s trapped in the adsorbant, which leads to a great underestimation of the real alcohol concentration.  If you've used OSHA 7 or a similar method to measure alcohols in the past, repent since it gives false negative and feel good that OSHA 5001 is here. Please note that methanol is collected by the standard sampling badge but has a much higher sampling rate than other alcohols.  SKC offers a specific sampler (575-007 with the green cover) for methanol that has a lower collection rate than the standard sampler, making it useful for the measurement of high concentrations of methanol near the OSHA limit of 200 PPM for 8h.  At this concentration, standard samplers will become saturated and give false readings.
