    Article Snippet: In the present contribution, the development of an high performance liquid chromatography– diode array detector and gas chromatography–flameionisation detectors method for the quantification of 53 active substances, 15 co-formulants and 8 impurities in plant protection products is described.. The confirmation of the results was performed by comparison of UV spectra or MS spectra of calibration solutions and sample solutions.. The method is universally applicable, simple, reliable and fast.

For SPME analysis, an Agilent Technologies gas chromatograph-mass spectrometer (GCMS) system (GC model 6890 N, MS model 5975 series B; Agilent Technologies Inc., Palo Alto, CA, USA) equipped with a Combi PAL robotic auto sampler (CTC Analytics AG, Zwingen, Switzerland) and a hot splitless injector (temperature 260 C, splitless time 1 min; Gerstel, Mülheim, Germany) was used. .. The SPME fiber, coated with carboxen/polydimethylsiloxane (CAR/PDMS StableFlex fibre, phase thickness 85 lm, length 1 cm; Supelco, Bellefonte, Pa, USA), was preconditioned prior to analysis at 270 C for 1.5 h. Samples (1.0 g each) were placed in 20-mL headspace vials (Grace Davidson Discovery Sciences, Rowville, VIC, Australia), along with 1 lL of internal standard (IS) solution (2-methyl-3-heptanone, 0.035 mg, and 2-ethyl butanoic acid, 0.071 mg, per 10 mL of methanol).
