Utilizing a combination of precise gas flow control, exact pressure measurements, and an ultra-inert flow path, the 4700 is capable of performing multistage dilutions for achieving standards ranging from part-per-billion to low part-per-trillion. The 4700 works with canisters and Bottle-Vacs to create dilutions up to 100x, and then allows a second dilution of up to another 100x to yield a total 2 step dilution of up to 10,000x. The 4700 uses precise pressure control, rather than mass flow controllers to meter in the standard. This approach has several advantages.First, very little of the standard mix is used in making a standard. This allows the original cylinder to last longer, keeping cylinder pressures higher where contents are more stable. Secondly, the mixing region required in a dynamic diluter is eliminated, substantially reducing surface area and carryover.With the 4700, small 110L cylinders at 1PPM will allow over 15,000 6L canisters to be filled to atmospheric pressure with a 1PPB mixture by first making a 20PPB working standard that can be further diluted into each canister to be tested. This results in just pennies worth of standard being consumed when performing inertness testing of canisters every 1-2 years. By contrast, typical dynamic diluters that must balance flows and pressures can typically only fill 50–100 6L canisters per high concentration cylinder, making field canister inertness testing prohibitively expensive. Low pressure standards or even samples can be further diluted using inlet #6 which is conveniently located on the front of the 4700. Easily perform up to a 100x dilution into a 6L canister, or up to a 40x dilution into a Bottle-Vac to obtain working concentrations that are more acceptable to GCMS inlet systems.订货信息：DESCRIPTIONPART #UNIT4700 PrecisionDiluter(Includes 6 channels)4700EA4700 TabletOption4700-TSCEA4-Position110L Cylinder Holder40-44910EACalibrationStandardsDESCRIPTIONPART #UNIT1 PPM TO-14aStandard (110L Cylinder, 1700psig)40-45010EA1 PPM TO-15Subset Standard (110L Cylinder, 1700psig)40-45110EA1 PPM TO-15 Plus Standard (110L Cylinder, 1700psig)40-45115EA1 PPM 4Component Internal Standard (110L Cylinder, 1700psig)40-45210EA2–5 PPM Carbonyl Standard (800L Cylinder, 2000psig)40-45130EA77-84 CmpdTO15 Standard (800L Cylinder, 2000psig)40-45120EA77-84 CmpdTO-15 Standard (w/ Formaldehyde) (800L Cylinder, 2000psig)40-45120WFEA4-PositionCylinder Holder (for 110L Standard Cylinders)40-44910EAHigh PurityStainless Regulator w/ CGA18040-02001EA
