EPA method 8330 is used to measure explosives residues in water and soil samples, using HPLC with UV detection. Target analytes are nitroaromatic and nitramine explosives and their degradation products. Obtaining pure, neat compounds for Method 8330 reference standards can be very difficult. To ensure the highest quality standards, Restek's Quality Control (QC) lab confirms the identity and purity of mixture components and solvents using one or more of the following techniques: GC-FID, HPLC, GC-ECD, GC-MS, LC-MS, refractive index, and melting point.

8330 calibration mix #1 contains 1,3-dinitrobenzene, 2,4-dinitrotoluene, HMX, nitrobenzene, RDX, 1,3,5-trinitrobenzene, 2,4,6-trinitrotoluene.
