Exciting news in the world of FTIR spectroscopy!
Agilent has just released MicroLab 5.8 , MicroLab Pharma 5.8 , and MicroLab Expert 1.3 —the software that powers the Cary 630 FTIR spectrometer and Agilent’s handheld and mobile FTIR systems . MicroLab…
Hi Margot,
It may well be that the column performance has deteriorated so much within the 7 months that the EasiVial standards are measured with poorer PDI values. The column performance can be tested with regular plate count determinations. It is a…
Hi sojeong,
every test report, delivered with aour columns, contains multiple specifications, but they are all measured with specialized systems and software. That means you might not be able to reproduce them identically. BTW for plate count you also…
Hi, I cannot configure the column compartment (CC) as it came integrated with the vial sampler on LC1290. We have the G7129B model for the integrated vial sampler and CC. I tried adding the column compartment details from the instrument configuration…
When the tuning is done at 3200 (+) everything is fine. When I change it to tune at 1700 (+) the masses are reasonably accurate. After it gets to the third mass (620) it appears that the entire spectrum shifts by about 1.5 AMU and the tuning fails. There…
Hi Siddhartha,
Thank you for contacting Cell Analysis Technical Support. Can you please go ahead and send us your System Files so that we can see what might be going on? These can be accessed in the Help Section of the Wave software. You can select…
Hello thank you very much for your response, thanks for the firmware data, the degasser worked perfect, the firmware change no longer, and I can not find the previous version. and are from the 6.80, but how is it possible that a team of thousands of dollars…
Thanks for the reply. I am monitoring at 254 nm. Higher wavelengths do not show that drift. It must be related to the THF (I am using unstabilized) but I do not see how.
