The SPME Troubleshooting Playbook 1 / 15

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.
