Potchefstroom, South Africa. It was a new system but had major issues (electronics) from day 1. Hopefully some one will be able to send me the guidelines of how to change the coil springs
Steps to possibly resolve the “No HPCHEM directory found” error try these three options:
1. Check the ChemStation Version Compatibility: Ensure that the UV-Vis Configuration Editor version you’re trying to install is compatible with your ChemStation…
In spectroscopy, the quality of spectral data depends greatly on the incident beam that passes through the sample being analyzed. For samples analyzed at large angles of incidence (AOI), such as bandpass and edge filters (e.g., beam splitters), maintaining…
In my case, the problem was due to an account that could not log in to the company-specific drive where all measurement results are saved. If you have the same problem, try another account and it should work.
I will list a few common errors with this. If it isn't one of the common errors, you may need to get tech support involved to fix it because the software may not be working properly.
