8330 calibration mix #1 (7 components)

Catalog Number: (REST31450)
Supplier: Restek
Description: 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.

Agarose, Electran, high resolution for electrophoresis

Supplier: VWR Chemicals
Description: Agarose high resolution (HR) has melting, max. 90 °C, and gelling temperatures (32,5 to 38 °C), but differs from traditional low melting point molecular biology grade agaroses in the gel separation range. Using this agarose in electrophoresis allows fine and consistent resolution of nucleic acids below 1000 base pairs, which differ by only a few base pairs. The properties of Agarose HR allow consistent gel separations (analytical and preparative) and performance of <i>in-vitro</i> translation and transcription mapping, as well as <i>in-vivo</i> ligation and transformation. For analytical gel separation of DNA/RNA below 1000 base pairs, where a higher gel strength for ease of manipulation is required, we recommend the use of Agarose, high resolution, Electran (43655).
