KIMAX® Chromatography Column with Reservoir and PTFE Stopcock
KIMAX column with a 250 mL reservoir at the top of the column. Reinforced top and a tooled lower end of the column for extra strength and a tight, leakproof fit with an all-PTFE stopcock. An "O" ring has been added under the PTFE fitment to maintain a liquid tight seal over a large temperature range (0-100°C). Liquid contacts only glass and PTFE. Stopcock is easily removed, providing easy access to column packing. Tip and stopcock assembly are available as replacement components.[…] Kimble Glass

ETP Electron Multipliers from SGE are air-stable. These Magnetic Sector electron multipliers can be repeatedly exposed to the atmosphere without degradation and can be stored on the shelf for up to two years. Total compatibility with all major Magnetic Sector instruments. SGE
BP624 Cyanopropylphenyl Polysiloxane GC Column. SGE
The BP624 has a polar phase used for EPA volatile organics analysis (EPA 624, SW-846 8240/8260), alcohol analysis and for USP G43. Temperature range is 0 to 240° C. Suitable replacement for: DB-624, Rtx Volatiles, VOCOL. SGE
TOF-MS Electron Multipliers. SGE
ETP Electron Multipliers from SGE achieve maximum performance for TOF-MS applications through optimized ion and electron optics and unique dynode shapes. The multi-dynode approach of all ETP Electron Multipliers result in longer lifetimes and better sensitivity compared with channel multipliers because of greater surface area. Increased surface area for enhanced sensitivity and extended operational life. Total compatibility with all major TOF instruments. SGE
BPX1 100% Dimethyl Polysiloxane GC Columns. SGE
A 100% polydimethylsiloxane non-polar column for Simulated Distillation in the petroleum industry. This column is coated with a custom-designed phase which gives low, consistent bleed and is ideal for background subtraction. The column is used for ASTM methods D2887 and D6352 and has a maximum temperature up to 430°C for the aluminum clad column. Suitable replacement for: DB-2887, DB-HT Sims Dis, HP-1, Petrocol 2887, Petrocol EX2887, Rtx-2887. SGE
HT8 8% Phenyl Polycarborane-siloxane GC Column. SGE
The HT8 has a unique high temperature phase suited for the analysis of PolyChlorinated Biphenyl (PCB) congeners. The unique polarity of this phase gives excellent separation of PCB congeners. Temperature range is -20 to 370° C. SGE
gc-BackFlush System. SGE
The BackFlush system eliminates the need to "bake" heavy sample fractions off the capillary column. Oils, tars and other semi volatile matter can be flushed back out of the injection port while the oven remains at a relatively low temperature. This increases column lifetime dramatically. Run times will also be significantly shorter because the system allows the run to be terminated as soon as the compounds of interest have eluted from the column, with everything else being flushed out[…] SGE
Ms NoVent™ II Column Changing Aid. SGE
The ms NoVent™ II interface is designed to allow column, liner or septum change-over, or column maintenance, to be carried out without the need to shut down the mass spectrometer. The design of the interface ensures NO air or water enters the mass spectrometer while the column is disconnected, unlike some devices that restrict the amount of air that enters the MS during changeover. This ensures the ion source remains contamination free. As a result, a column can be changed and the[…] SGE
ICP-MS Electron Multipliers. SGE
ETP Electron Multipliers from SGE are incorporated as original equipment in every major quadrupole and TOF ICP-MS instrument being manufactured today. They deliver optimized ion and electronic optics and unique dynode shapes for maximum performance. The multi-dynode approach of all ETP Electron Multipliers result in longer lifetimes and better sensitivity compared with channel multipliers because of greater surface area. Increased surface area for enhanced sensitivity and extended[…] SGE
