Extracted text: 6. You are supervising a sampling campaign and have received the following data with a note indicating that a technician is suspicious of one of the four (4) autosamplers being used, and is afraid that it might be malfunctioning (but did not indicate to you which sampler). Given that you are required to monitor the four sites continuously, and you don't have an extra autosampler available, 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 a 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?
