- by /u/massspec1973Are there any ToF users struggling with the need to frequently calibrate their detectors? I'm looking for advice and feedback on why and the implications on data confidence or throughput. thanks submitted by /u/massspec1973 [link] [comments]
- by /u/Separate_Issue_6572also can u tell me what autosampler u use today and if u have had any issues with it submitted by /u/Separate_Issue_6572 [link] [comments]
- by /u/Ok-Emu3337Hello All, Recently I had a problem with Thermo Element-XR ICP-MS whereby the high voltage is not turning on. Previously we had vacuum leak in the interface region and got it fixed. Afterwards, we turned on the plasma, all LED indicators at the system control panel are all green, only the HV electronic was red and not be able to measure anything. We did some PC and instrument reset but no improvement. My lab friend suspect there was no communication between Front End PC with the ICP-MS, however, only HV is not responding. Does anyone experienced this and have any […]
- by /u/Key_Sprinkles_4541Method: acylcarnitine quantitation via FIA-MSMS Inquiry: suppose I’ve optimized C8 and D3-C8 from pure standards and I want to include C8:1 for my acquisition but either do not have the standard or can’t afford to buy it. Do I choose the analytes internal standard parameters or the closest in mass /structure? My main concern is all the dicarboxylics that I can’t obtain in mixes submitted by /u/Key_Sprinkles_4541 [link] [comments]
- by /u/Loud_Side3293I'm pretty new to the mass spectrometry world and I'm trying to meet more people in the field. What was the last place you interacted with other people in the MS community? Reddit, LinkedIn, Discord, Slack, conferences, or somewhere else? Just curious where everyone actually hangs out. submitted by /u/Loud_Side3293 [link] [comments]

- by /u/Separate_Issue_6572I'm a bit overwhelmed by how complex mass spectrometry seems, what's the smallest or simplest tool you have used alongside a mass spectrometer? Anything counts. even if its just a brush u use to clean the mass spec submitted by /u/Separate_Issue_6572 [link] [comments]

- by /u/mage1413Hi all, I was trying to perform an autotune and ran into this message. From my understanding I will need to perform some sort of quad dipping. Ive done it before on triple quads but not on a single quad MS. At the moment Im running the older Chemstation and could not find any options on the diagnostic settings. I was wondering if anyone has done this on any of the single quad 6XXX series? Thank you. submitted by /u/mage1413 [link] [comments]
- by /u/MALDI_AtzeHello, I am trying to optimise the reflector negative-ion mode on a Bruker Microflex MALDI. I need high resolution for the isotope distribution of oligos in a mass range up to 3500 Da. The spectrum above was acquired using the following parameters: – Pulse Ion Extraction delay: 510 ns – freq: 12.0 Hz, – Ion Source1: 18.9kV, – Ion Source2: 88.1% – Laser intensity: 84% Does anyone have any tips on this? Thanks in advance 🙂 submitted by /u/MALDI_Atze [link] [comments]
