The SPME troubleshooting playbook
Seven symptoms, what to check first for each, and the source behind every fix. The first 2 pages are open below. Put in your email to get all 15 as a PDF.
What's inside
- Ghost peaks and carryover, and the 2-minute cleaning step that fixed it in one published study
- Fibres that break, broad or split peaks, and analytes that barely extract
- Poor precision, and why agitation is part of the method
- Recovery that drifts down, and what damages a coating
- Matrix results that don't match water standards: three cases from my binding-matrix modelling
- Reference pages: calibration choice, fibre coatings, conditioning limits, QC from EPA 8272, a printable fibre log
My Ph.D. was on SPME in Janusz Pawliszyn's lab at the University of Waterloo.
