We have the Cary 630 FTIR with the Microlab PC and Microlab Expert software products
Many years of using the system still hasn't resolved many of the issues we have encountered. We use other FTIR products that cause far fewer issues than the Microlab products. People avoid using the Cary 630
It came to a head today. I ran an ATR of a known compound (A) and couldn't obtain a library match - fair enough it happens so I made a new library (CHEM) that just contains the spectrum of compound A I ran.
I then ran a library search of my spectrum with several libraries including the new library (CHEM) with just my spectrum in it. Guess what. My spectrum of compound A doesn't match to the spectrum of A in the CHEM library I just created even though it should be identical.
What is going on?
Thanks in advance
