OSHA 125 |
Metals |
All ICP metals are analyzed following OSHA 125 Modified. However, the sample prep changes depending on metals requested and collection media: Analyses which include either Silver, Antimony, Tin, Iron or Titanium are prepared using a modification of NIOSH 7303 and OSHA 206 (Hydrochloric and Nitric acids used in Hot Block digestion, final sample - matrix 20% Hydrochloric acid.) Others (MCE, PVC, Ghost wipes) are prepared using a modification of NIOSH 7082 and OSHA 121. (Nitric acid used in Hot Block digestion, final sample matrix - 5% Nitric acid.). For Non-dissolving wipes (Smear Tabs), the preparation is a modification of NIOSH 7105. (Hydrochloric (if Ag, Sb, Sn, Fe, Ti included) and Nitric acids with 30% hydrogen peroxide digested on hot plate.) ELLAP Ghost Wipes are prepared using modifications of NIOSH 9102 and NIOSH 7303 (Hydrochloric and Nitric Acids, final sample matrix – 10% HNO3, 4% HCl. |
