I have recently ran two standards on the Cary 630 FT-IR using the ATR module - qualitative search. One is Heptanes and the other is N-Heptane.
I then ran four samples - three were N-Heptane, the other was Heptanes and compared them to the two standards…
megaflorch - this was fairly old topic and I wasn't sure if you completed your standards/sample prep. I use a similar technique to get my analytes within a better working linear range with respect to my GC-FID. Your logic is good.... here is my standard…
I went through everything I could find, but it appears that BootP doesn't work properly in Windows 10 and even when you follow the instructions it fails. As I mentioned above, the only way I found to get it working was to replace the JetDirect card with…
I am having trouble separating methyl methacrylate (MMA) from another peak. The interfering compound, appearing in the front, is identified by library as 3,3-dimethyl-2-butanone and it is inherent to the sample. MMA appears as the split/tailing peak.…
I have Chemstation C.01.08 [210]. Whenever I try to run a partial sequence, I get the 'Initialization of Sequence Failed' error message. From what I could find online, that issue was supposed to be solved in C.01.08 version of the software. I have Unique…
You can definitely set up an intelligent report to do what you want, but there is a much easier way to do this in OpenLAB ChemStation. When you create a calibration table, ChemStation gives you an option to 'Calculate Signals Separately': When selected…
Hi,
I am currently running a USP <467> protocol which monitors the recovery of: methanol, ethanol, acetone, isopropyl alcohol, hexanes, and toluene. I make a standard solution using DMAC with known amounts of solvent and use the same solution to spike…
I did a lens ramp on the failed BFB_AT and the emission ramp for 50 amu was very choppy. Setting the emission at 50 amu is where the tune process fails. Could this be due to a hardware problem?
Hi Lakshmi, Here is the reply from our compliance group.... Traceability and Audit Trails Data are generated by the same native chromatography data system (CDS) used in the daily operation of the instrument, which controls the system being qualified during…
Hi,
Every time we vent and vacuum down the MS2 auto tune fails with the high mass.
I've tried to tune from factory settings and manual tune using a file that was used prior to the shutdown.
The instrument is second hand so we have had the vendor…
