Water determination in gases and LPG


RPV VALVES

The Aquamax KF PRO LPG is designed for an easy and accurate determination of water in liquefied and gaseous samples such as LPG and LNG.

The device combines coulometric Karl Fischer method with an unique gas evaporation and dosing procedure.

The Aquamax KF PRO LPG includes all features required for ppm level water in LPG and Gas, including the sulphur removal cartridge eliminating all side reactions and our sample loop principle allowing you to fully automate the measurements, up to 125 per day!

The unique ECH sample loop allows you to use the instrument in your laboratory with full automation, as a portable/field use analyzer or can be integrated in to your process as an on-line system

Key advantages

  • Sulfur removal cartridge eliminating all side reactions
  • No interference calculation required
  • Totally automated process, no operator input required for the test
  • 250 measurements can be performed in 48 hours
  • No balance is required
  • Suitable to test all gas types without any calibration or adjustments
  • No separate rinsing gas is required
  • Rinsing process is fully automated
  • High sample throughput and long reagent life
  • Compact device

Features and Results

  • Determination of moisture in liquefied and gaseous samples
  • Determination of pressure in the sample loop
  • Inlet pressure up to 200 bar/2900 psi Automatic pressure regulation
  • Transfer line with direct injection
  • Automatic rinsing bypass and steps for rinsing
  • Measuring cell without diaphragm (only one electrolyte required)
  • Setting of application-specific methods
  • Avoiding of side reactions by Sulphur trap
  • Type of result: µg, ppm (gas volume), Vppm, Mppm, Mol ppm by using the formula generator

Accessories 

  • Typical sample cylinder with valve, e. g. of DME.
  • Example of a 5 L Propane Cylinder.
