The Entech Instruments 4700 Precision Diluter offers a combination of precise gas flow control, exact pressure measurements, and an ultra-inert flow path, making it 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 Entech Instruments 4700 Precision Diluter 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.

Features:

  • 6 channels standard, enabling dedicated internal standards and calibration standards
  • Easily performs 1-100x dilutions, or dilutions up to 10,000x
  • Dilutes high concentrations, such as soil gas, with ease
  • Able to create 1PPB challenge standards for 6L canister inertness validation tests
