I'm hoping someone can help me understand the library match factors from Quant MH B.08. The attached pdf shows 3 examples. In the first example, the match factor or match score of 89 makes sense to me. Most of the masses are present and there are no extra masses in the unknown spectrum (top). The middle overlay shows a match of 41.5. This… Show more
I am using the new OLCDS 2.4 software while performing an OQPV. It is important to have the numerical information of the UV spectrum in order to evaluate the wavelength accuracy in several points. I know how to export UV spectrums in CS or EZChrom but I can't find the application in CDS 2.4. I would like to know how can I do it in the new software… Show more
Im sorry, I just thought you can select a table with the values. Then filter for the values you need, and let the programm create a csv file. But they replied that its impossible. It was just an idea. I was able to do this step in OpenLabs for the Amount. I wanted to put only the Amount in the CSV file. That worked. i mistakenly…

Last week we vented and powered off our Agilent 6650 iFunnel QTOF. When we tried to turn it on and pump down from mass hunter software (I think B 09), the rough pump ran at the beginning, but just after 10 min, then it automatically stops. After a couple of hours the The TOF Vac showed 9.94 E-01 Torr, the Quad Vac showed 8.56E-10 Torr and the… Show more
Everytime I try to run a sequence it immediately aborts. I am using a GC 7890A with chemstation OpenLab c.01.09. The message on the front of the instrument reads front inlet valve purging. I am able to run a single injection, but not a sequence even after hitting 'prep run'. How do I fix this issue so that i can start a sequence?
Hi, The fault light on our injection tower keeps flashing. I counted it and its 4 flashes. Anyone knows what this means? Been trying to find it online but have had no luck! Thanks, Caroline
Hi everyone, I'm having some problem with my method. Not sure exactly what it is: Couple of days ago I've replaced the column of my GC-6850 with a shorter column ( 30m - 320mm). I had to integrate the peaks with the new length of the column. I normally use two methods to run my samples: One is longer (ramp) and the other one is shorter… Show more

Hi I had a question about GC MS Split (gc to FID/MS). I have a thermo splitter that has no auxillary flow to counteract the ms vaccuum, but want to change out the capillaries that come recommended with the splitter. The recommended capillary dimensions for the FID Capillary is 60cm with 170um /0.363 mm and the MS capillary is 240cm with… Show more
