FOUNDED 1993 PIONEERS IN IR-FIBER AND REACTION MONITORING Probe Heads MATERIALS OF CONSTRUCTION

• The standard material of construction for liquid contact in Remspec's probes is 316 SS with seals made of Kalrez®: or graphite filled polymer.
• For more aggressive environments we offer Hastelloy®: C2000 which has superior properties to the commonly used C-276 alloy.
• Probe head bodies can also be fabricated in basically any machinable material including, some polymers, titanium, nickel, and even tantalum.

HD-20 High Pressure ATR Process Probe INFRARED CRYSTAL MATERIALS Remspec offers a range of crystal materials so that the best option can be selected:

• Cleartran. Military grade ZnS It has excellent resistance to bases and acids
• ZnSe has a wider optical window than ZnS but is not as resistant to bases and strong acids
• AMTIR Withstands fuming sulphuric without any problems but is attacked in strong base
• Si or Ge Both have lowered sensitivity due to their high refractive indicies. Ge absorbs light at elevated temperatures and Si has a limited spectral range
• ZrO₂ is highly chemically resistant but has a limited spectral range
• Diamond. Diamond is brittle, very expensive and has a large low signal region due to a C-C fundamental vibration and hydrogen contamination. It is however resistant to most most strong oxidizers
