Varian 1200L LC/MS GC/MS - Agilent Technologies

Ammonia 5.0 Research Grade (99.999% purity)A two-stage, 0−15 psi (0−1 bar) pressure regulator that has a stainless steel diaphragm isrecommended. The output pressure to the 1200 MS should be set to 3−5 psi (0.2−0.3 bar). Gaslines for ammonia should be made of stainless steel. All gas lines should be free of oil andpreferably flame treated or solvent washed.Ammonia, Anhydrous (CAS Number 7664-41-7)Anhydrous Ammonia gas is highly toxic. Inhalation may cause irritation to eyes andthroat and may cause pulmonary edema, which can result in serious injury or death.Repeated exposure to Anhydrous Ammonia may cause permanent lung damage.• Refer to Material Safety Data Sheet (MSDS) for Anhydrous Ammonia forexposure control/personal protection, handling/storage, accidental release,first aid, and fire fighting measure requirements.• Anhydrous Ammonia should only be used in conjunction with an appropriateventilation system for the instrument, the exhaust from the foreline pump, andthe gas cylinder. Use appropriate safety shutoff valves for the AnhydrousAmmonia supply and interconnecting lines.The operator is responsible for determining and implementing appropriate precautionswhen using Anhydrous Ammonia and for compliance with all governmentalregulations. It is the operator's responsibility to understand and adhere to all safelaboratory practices concerning the use of toxic gases, including Anhydrous Ammonia.CID Gas (Triple Quad only)Argon is recommended for use as a collision gas for Collision Induced Dissociation (CID)MS/MS in the triple quadrupole MS, with typical flow rates of 1 mL/min. The argon must have apurity of greater than 99%, and be regulated to 5 psi.GC Carrier GasesHeliumHelium is required as a carrier gas for the GC, with a minimum of 99.999% ultra-high purity, andless than 1.0 ppm each of water, oxygen, and total hydrocarbons. The minimum requirement isone 257 ft 3 tank with an Alltech regulator #AL8111, or equivalent tank and regulator.The presence of greater than 1 ppm oxygen or water in the carrier gas supply maysignificantly affect the performance of the 1200 GC/MS. It may also damage suchcomponents as the capillary column, filaments, and multiplier. Varian recommends thatyou verify that your gas suppliers use controlled tanks to ensure that purity standardsare maintained. If you purchase pure gases in contaminated tanks, you may end up witha contaminated system requiring costly and time-consuming repair.03-914961-00:6 9 of 24 1200/1200L MS Pre-installation Instructions
