Ideal for initial method evaluations and ongoing method performance validations. Analytes are divided into three ampuls based on compatibility for maximum stability and shelf life.* Precise formulations improve data quality and operational efficiency; spend more time running samples and less time sourcing and preparing standards. Quantitatively analyzed to confirm the composition and stability of each mixture. *When combining compounds with different functionalities, chemical stability can be an issue. The analytes in this kit are separated into three mixes to ensure maximum long-term storage stability. For analysis, a fresh working standard should be prepared by combining the three kit mixes in a 1:1:1 ratio to prepare a 100 µg/mL working standard solution. Once blended, Restek does not recommend storing working standards or subsequent dilutions for future use. Contains 1 mL each of these mixtures. 31153: QuEChERS Performance Standard A 31154: QuEChERS Performance Standard B 31155: QuEChERS Performance Standard C View Product Information

8330 Internal Standard (3,4-Dinitrotoluene) EPA Method 8330 is used to measure explosives residues in water and soil samples, using HPLC with UV detection.¹ 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.
