Given that you are required to monitor the four sites continuously, and you don't have an extra autosampler availab pulling the sampler from the field for inspection would require leasing an additional autosampler and getting it deployed. You do not have sufficient budget to rent more than 2 aux samplers at time. What should you do? Hints: 1) Are there any indicators in the provided data that one of the autosamplers may be behaving in a manner that is different from the others?
