Updated EPA Method 524.3 Purgeable Organic Compounds by GC/MS
   

The updated EPA Method 524.3 for the Measurement of Purgeable Organic Compounds in Water includes 18 analytes added to the Method 502.2 base of 54 liquid plus 6 gas analytes.  AccuStandard has introduced the first complete set of Certified Reference Standards for this new GC/MS method. The set of standards available includes the 18 component mix, the internal standard, the surrogate standard, and a combination of both the internal and the surrogate standards.
