Dumb Cheesewedge project edition<p>Time to figure out how this this shimadzu GC-14A gas chromatograph works. </p><p>Except for the keypad the unit seems in pretty good physical condition, and the damage to the keypad seems to be superficial only so that's good.</p><p>Turning on the power switch the unit springs to live. The large fan circulating chamber air is definitely louder than expected but is tolerable with the door shut.</p><p>With the heaters turned on the unit quickly stabilises to a chamber temp of around 25C (7C above ambient) and holds it. This is good as I don't want to heat the column too much, as it is likely filled with air and might be damaged if heated without purging first, but shows that at least the heating section is fully functional.</p><p>The control unit also seems to operate as expected, with the VFD seven segment display still being nice and bright and seemingly all buttons working and it displaying chamber temperature. It will take a few more hours with the manual tho until I can actually understand how to operate it.</p><p>This unit was bought untested for little money, so that is fantastic news, I was half expecting to find a dead lump of metal.</p><p>Here are some initial pictures:</p><p><a href="https://infosec.exchange/tags/analyticalChemistry" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>analyticalChemistry</span></a> <a href="https://infosec.exchange/tags/chemistry" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>chemistry</span></a> <a href="https://infosec.exchange/tags/gasChromatography" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>gasChromatography</span></a> <a href="https://infosec.exchange/tags/shimadzu" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>shimadzu</span></a></p>
