Hıyarda Bazı Bitki Gelişim Düzenleyici Kalıntılarının QuEChERS Analiz Yöntemi ile Metot Validasyonu

Method validation was performed by QuEChERS method to determine the plant growth regulators abscisic acid, giberallic acid and paclobutrazole residues using LC-MS/MS. The validated according limit of detection (LOD), limits quantification (LOQ), linearity, accuracy recovery. Calibration with matrix used elimination effect. linearity three PGR were determined range 10-200 μg mL-1. All correlation coefficients (r2) greater than 0.999. LODs between 1.31 1.70 (LOQ) varied 4.38 5,68 recovery fortified cucumber samples in gibberallic at different concentrations (10, 50 ve 100 mL-1) conducted. For repeatability, relative standard deviation (RSD%) ranged from 1.66 11.61, for reproducibility, RSD% 3.40 9.78. overall 105.41% RSD 6.60% (n=540). results compatible values specified SANTE/11813/2017 (70–120%) repeatability (RSD% ≤ 20%).
