Good morning everyone. Does a physical test (such as "color of solution") need double checking by another analyst?

If you investigate according to ISO standard - do as relevant standard states.
Same if your source method is ASTM method, EPA method, SOP etc.

If none of above apply do as to obtain best results.
Depends whether some a**hole defense attorney starts screaming about it. Or whether one had a witness when he used the restroom.....
Yes, I have a problem with an inspector.
According to your MAJOR OBSERVATION, each analysis should be done by 2 analysts.
If you work in a crime laboratory then they probably require it. Just like to show a white powder is cocaine you have to run it by mass spec and FTIR, must be two different methods to confirm even though mass spec should be reliable enough on its own.

Just like with FDA, if you change the autosampler tray to a different serial number you have to revalidate the entire system because it is now a different instrument, even though the tray only moves the sample into position and has no effect on the result.

Too many lawyers and not enough scientist deciding what constitutes good data.
The past is there to guide us into the future, not to dwell in.
