- by /u/Cheap-Ad-2889Hello Y’all, I am an undergraduate researcher in Chemistry and I desperately need help with molecular docking using PLANTS software + chimera with an application in PyMol. I feel I have a general understanding on the topic as I have been able to dock before. I am terrible with computers and troubleshooting with softwear is extremely difficult for me. My main deal right now is getting my ligand file doc ready for PyMol but I keep getting errors. I’ve done research on it, YouTube, Tik tok, friends, and chat gtp but none are helpful. If someone could please give any […]

- by /u/7Cneo7Hi everyone, I’m working with historical physico-chemical water quality data (pH, conductivity, hardness, alkalinity, iron, free chlorine, turbidity, etc.) from systems such as cooling towers, boilers, and domestic hot and cold water. The data comes from water samples collected on site and later analyzed in the laboratory (not continuous sensors), so each observation is a snapshot taken at a given date. For many installations, I therefore have repeated measurements over time. I do have experience interpreting PCA results, but mostly in situations where each system is represented by a single sample at a single point in time. Here, the fact […]

- by /u/vietbabyxI’m a new faculty member and inherited a Shimadzu FTIR and an Agilent GC/MS that haven’t been used in years. There are no SOPs, no instructions, no software guides and no one on campus who knows how to run them. I’m trying to figure out how to actually operate them, both the hardware and the software. I don’t know where to start. Any advice would be greatly appreciated! submitted by /u/vietbabyx [link] [comments]

- by /u/idkuralieHi, I'm new at my job and an hydrogen generator is not working because of a error "float chamber". The generator is a 20H from Parker haniffin and is used for a gc/fid. I tried to remove the water from the "separation chamber" but it is still not working. Does anyone of you know what I can do to resolve this issue? The generator is from 2014 and no maintenance or part replacement has been carried out since its installation. I contacted Parker and an other company answered but there are far from my location and kind of expensive. Sorry […]

- by /u/redhamster2009Is there a good way to clean distillation glassware? Im using a vacuum distillation instrument and I can never get the boiling or receiving flask totally clean. There is some dark residue from overheating boiling chips, and a film that never goes away. Per the ASTM method, im using toluene to clean the system, and then I rinse the glassware in soapy water and finish with IPA. Reluctant to scrub at all since it is used under vacuum. submitted by /u/redhamster2009 [link] [comments]
