Elmalarda İmidacloprid ve Dimethoate Kalıntıları için QuEChERS ve LC–MS/MS ile Metot Validasyonu

Year 2017, Volume: 5 Issue: 1, 29 - 37, 01.08.2017

Abstract

Pestisit kalıntı
analizlerinde kullanılan tüm metotların, orijinal laboratuvar örneklerinin
analizinden önce validasyonu yapılmalıdır. Bu çalışmada elmalarda
imidacloprid
ve dimethoate kalıntı analizi için analiz prosedürünü valide edilmesi amaçlanmıştır.
Bu amaçla hiçbir ilaçlama yapılmamış
Golden
Delicious ve Starking Delicious
elma örnekleri homojenize edilmiş ve
pestisitlerle 3 farklı seviyede zenginleştirilmiştir. 10 g elma örneği QuEChERS
yöntemi ile ekstraksiyon ve clean up işlemine tabi tutulmuştur. Sonra
LC-MS/MS sisteminde
imidacloprid ve dimethoate analizleri yapılmıştır. Her iki pestisit ve elma
çeşiti için matris etkisi önemli bulunduğundan, miktarsal hesaplama matrisli
kalibrasyon (MC) ile yapılmıştır. Analiz metodunun validasyonu, geri alım,
metot dedeksiyon limiti, tekrar edilebilirlik, kesinlik gibi metot performans
kriterleri ile gerçekleştirilmiş ve tümü olması gereken limitler içinde bulunmuştur.
Her iki elma çeşiti için imidacloprid ve dimethoate
geri alım değeri ortalaması %88.34 (RSD %7.72) olarak bulunmuştur. Tüm metodun
geri alımı ise  %89.50 (RSD %12.02) olarak
bulunmuştur (n
= 150).
Bu rakamlar olması gereken ortalama geri alım (%70–120) ve
tekrar
edilebilirlik  (RSD ≤ %20) değerleri ile
uyumludur
. Pestisitlerin
metot dedeksiyon limiti,  AB ve Türk Gıda
Kodeksi MRL değerlerinden düşük bulunmuştur. Her iki pestisit için kalibrasyon eğrisi
5–200 ng/mL konsantrasyon
sınırlarında doğrusal bulunmuştur.
