Rtx-200 columns have accomplished many difficult separations. The trifluoropropylmethyl polysiloxane stationary phase has a unique selectivity that changes elution orders and resolves compounds that phenyl, cyano, or carbowax phases can not. These columns offer exceptional thermal stability, low bleed, and superior inertness - even for active compounds such as phenols, and with sensitive detectors such as ECDs, NPDs, and MSDs.

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.
