SP 2000 GPC System Compact, Efficient, and Affordable The Model SP 2000 GPC Cleanup System is the simple and economical solution for GPC cleanup. This manually-operated, highly-affordable instrument uses the same columns as our GPC AutoPrep 2000 and achieves the same precise results. The SP 2000 is designed specifically for customers with small sample load requirements. The Model SP 2000 consists of an isocratic HPLC pump, sample injector, switching valve, and control module. After manual injection into a calibrated sample loop, manually switch the valve to the inject position to introduce the...

RapidVap N2 Evaporation Systems Automated, Fast Evaporation Rates, Greater Throughput The RapidVap N2 Evaporation Systems offer a more efficient, automated alternative to Kuderna-Danish and rotary evaporators and may be used with a broad range of aggressive chemicals. The RapidVap N2 System directs a stream of nitrogen or dry gas downward onto the sample surface. Nitrogen blow down reduces the partial pressure directly over the liquid to speed evaporation and help remove solvent as it evaporates. Program nitrogen for 2, 4, 6, or all 8 tube locations. Apply vortex motion and dry heat to further...

High Performance Gas Chromatography Detectors and Systems for Pesticides Analysis One of the most challenging analytical applications involves low-level pesticide residue analysis. The sample matrices are often complex, particularly when extracts from many foods or plants contain large numbers of possible interfering compounds. OI Analytical offers Pesticides Analysis Systems developed specifically to detect organochlorine, organophosphorus, and organosulfur pesticides using OI Analytical’s market-leading selective detector technology: Pulsed Flame Photometric Detector (PFPD), Halogen Specific...
