both sample types, which mimics the good compromise provided
by the official QuEChERS versions for base and acidic-sensitive pesticides.
3.2. Method comparison with spiked apple samples
As shown in Fig. 1, consistent pH stability was achieved when
using 5% (v/v) of acid in MeCN with 7.5 g of the ammonium salt,
particularly for the acetate buffer. Recovery experiments were conducted for spiked samples at those conditions, with the aim to
compare the performance of both buffered versions. Furthermore,
the results were compared with the unbuffered NH4Cl version,
also using 7.5 g of salt and 15 mL of MeCN, and with AOAC Official Method 2007.01. Duplicate spikes were made each at 10 and
75 ng/g in apple. As listed in Section 2.5, the d-SPE step was used
for cleanup after the initial extraction, and for LPGC-MS/MS, analyte protectants were utilized to provide benefits in the analysis as
described previously

Pemulihan eksperimen dilakukan untuk berduri sample di syarat-syarat tersebut dengan tujuan untukmembandingkan performa kedua versi buffered. Selain itu,hasil dibandingkan dengan versi NH4Cl unbuffered,juga menggunakan 7.5 g garam dan 15 mL MeCN, dan dengan AOAC resmi metode 2007.01. Duplikat paku dibuat masing-masing 10 danng/g 75 di apple. Seperti yang tercantum dalam bagian 2,5, langkah d-SPE digunakanuntuk pembersihan setelah ekstraksi awal, dan LPGC-MS/MS, analyte protectants yang digunakan untuk memberikan manfaat dalam analisis sebagaidijelaskan sebelumnya
