875 KF Gas Analyzer: Fully Automated Water Analysis in Permanent and Liquified Gases

With its new 875 Karl Fischer Gas Analyzer, Metrohm combines decades of experience in moisture analysis and sample handling. The KF Gas Analyzer is designed to handle nearly any gas sample – compressed, liquefied or native. It is fully equipped to measure the absolute moisture content of LPG, petrochemical intermediates, natural gas or other compressed or liquefied gases.

Metrohm’s easy-to-use gas analyzer features a complete and integrated sample introduction and treatment system. The integrated sample heater guarantees uniform temperature and evaporation of a sample regardless of its original state while a precision flow control valve ensures a constant and even flow of the sample. A series of automatically controlled magnetic valves connect the sample to a rugged mass flow controller, which carefully meters the exact amount of gas specified for each analysis. The analyzer’s coulometric cell is powered by one of Metrohm’s lab favorites - the KF Titrando.

The system’s strict separation of gas-carrying system and electronic area ensure safe operation. Gasses are prevented from ever coming into contact with sparks, which eliminates the risk of gas explosion.

These key features and the KF Gas Analyzer’s robust design make it an ideal candidate for routine analysis in the laboratory. The system is controlled by Metrohm’s easy-to-use tiamo™ software and consists of a control unit and an analysis module.

Highlights:

  • Complete system with durable components for high flexibility
  • Separation of the gas handling system from the electronics and power supply for added safety
  • Sample inlet filter to keep out particulate matter
  • Venting bypass to release the pressure when swapping gases
  • Built-in evaporator for gasses in all states – native, compressed and liquid
  • Oil filter with flushing port to remove residual oil
  • Precise gas measurement with a mass flow controller (MFC)
  • Automated analysis sequence using magnetic valves
  • Predefined analytical methods with gas feed and pre- and post-flushing phase
  • All components integrated in one system

The 875 KF Gas Analyzer is supplied with predefined software methods, so measurement can begin immediately after installation.

Analysis of a wide range of liquefied or compressed gases, such as:

  • propane, propene, LPG, butane, butene, butadiene
  • dimethyl ether, ethylene oxide
  • chlorinated hydrocarbons: methyl chloride, ethyl chloride, vinyl chloride
  • refrigerants: various CFC, HFC, CFC
  • New and contaminated refrigerants containing refrigeration oils
  • Analysis of permanent gases, e.g. natural gas

Run Your Lab Like A Business

When looking at best practices for running a lab, things as seemingly diverse as staff development and retention, inventory management, procurement, and efficient use of training spends, need to be looked at together. After all, equipment is only as good as the staff who uses it and your staff is only as good as their training.

Halting Hackers

With headlines screaming about hacking, of the latest James Bond movie Skyfall most recently, of national and nuclear weapons laboratories not so long ago, and of businesses and individuals almost on a daily basis, it’s no surprise that worldwide information technology (IT) security spending is set to hit $77 billion in 2015—almost 8 percent more than this year’s $71 billion, according to IT researcher Gartner, Inc. 

Transporting Samples

When we think of labs and how they operate, we’re mostly focused on testing and subsequent results—the technicians’ abilities and conditions inside the facility where sample research and measurements take place. It’s less often that we focus on how the samples arrive at the facility. However, sample transport is an important part of a successful laboratory operation. A healthy and timely sample is vital to accurate analysis.
