WebOct 1, 2000 · Dilute-and-shoot preparation is commonly used for the determination of drugs in several biological matrices such as urine and saliva, but is not typically used with plasma samples because the amount of protein present in plasma can lead to a variety of problems including column failure. WebFeb 15, 2024 · This paper describes a dilute and shoot approach to determine five Alternaria toxins in selected food samples using liquid chromatography–tandem mass spectrometry (LC-MS/MS). ... Another aim of SPE is to avoid sample dilution during sample preparation; therefore, the low concentration levels (down to 1 µg/kg) can be … WebFor comparison purposes, two separate sample prep techniques were performed prior to LC-MS analysis: SPE using the Supel- Select SCX and a “dilute and shoot” technique. The Supel-Select SCX SPE method is detailed in Table 1. For the dilute and shoot sample, 500 µL of spiked urine was mixed with 500 µL of acetonitrile and analyzed directly by LC … build a better diamondhead
