We are all familiar with maintaining our lab instruments, but how often do we perform maintenance on our lab methods or SOPs?
Even with the absence of visible or even apparent issues, it is good to occasionally review testing methods with all technicians who operate a piece of equipment. Compare the standards that everyone has run in the last few weeks and see if there are any differences. No difference is too small! Look for accuracy, and any obvious differences in the data -- but also observe to see if there could be any changes to improve efficiency.
For more complicated equipment with multiple steps involved in loading a sample, the tiny details can sometimes make all the difference. For HPLC -- the order that you add solvents, and for rotational rheometers -- how you trim the sample and remove bubbles could be crucial in obtaining accurate data.
Ideally move towards instrumentation that removes as many sample handling steps as possible -- not only for data accuracy & consistency, but also to allow more time on important focuses such as the science and interpretation of your data.
