[QUOTE="lionpauu, post: 6849169, member: 732987"] [B]TL;DR Summary:[/B] Do Moon phases affect weighing precision on the microgram range, over several hours days at elevated temperatures? Hi, I'm looking to improve the precision of a system over a several hour cycle of operation of +50°C operation. The mass is ~11g and is suspended below the balance via a factory provided point. The "sample" is enclosed within a large borosilicate flask 150mm dia x 450 mm height that is trace heated the floor is also heated and all report a 0.1°C deviation from the setpoint of 50°C. The sample itself is monitored via a non-contact IR sensor and reports a 0.1g °C max variation. So the problem is that the sample will apparently [I]lose[/I] up to ~0.015 g [I]after[/I] achieving the temperature set point, and this drift will [I]continue[/I] for several hours. I have reduced this rate by better sealing the falsk to air ingress and also I think some of the system was accumulating a static charge. So my question is has anyone an explication of why the loss and recovery inverse to temperature, the loss in air density should [I]increase[/I] the apparent wt, could the lunar cycle be having an impact? My balance can resolve 0.0001g and I am logging the data remotely. There is more on my problem on twitter... [MEDIA=twitter]1612233786296774656[/MEDIA] [/QUOTE]
