Probe Heads for ReactionView® and ReactionProbe®

MATERIALS OF CONSTRUCTION The standard material of construction for liquid contact in Remspec's probes is 316 SS with seals made of graphite filled PTFE or other graphite filled polymeric material. For more aggressive environments we offer Hastelloy&trade 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. With tantalum it is just as effective and substantially more cost effective to use a thick layer of reactively deposited tantalum on a 316 SS base.

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.
