White Bear Photonics offers used FTIR sampling accessories for the Thermo Nicolet FTIRs. The Thermo Nicolet FTIRs have kept the sampling accessories backward compatible for over 30 years. As a result, older ATRs (left over from older FTIRs), can still be used in the most recent FTIR models. This allows used accessories to be rebuilt and re-qualified. Our inventory for used accessories is limited and based on (random) availability. If you do not find the accessory you need contact us.
We also have a small applications lab with most of the Thermo Nicolet models (which we support). This allows us to use and test various types of sampling accessories and determine which can provide the best results.
