Value based on a 25-mL sample volume. The minimum sampling volume needed to obtain the OSHA PEL at the LOQ for the element/compound at a sample digestion volume of 25 m L. The m aximum sampling volume for a given sample, calculated by taking 50,000 :g as th e lim it for the element/compound per sample. NOTE: The LOD and LOQ values are dependent on the particular analytical instrument used. Also, LOD and LOQ values may vary for a particular elemen t due to certain interelement interferences.
