方案详情:
Laboratories are looking beyond whether an instrument can ‘do the job’ to whether a specific instrument can improve their sample throughput, lower their costs, simplify sample preparation and instrument operation, and deliver reliable results throughout the analysis of a large batch of samples.
Complex matrices, such as steel samples, introduce a lot of chemical or physical interferences to flame atomic absorption spectroscopy measurements. Manual dilution of samples is the conventional way to prevent these interferences causing incorrect results. Unfortunately, such dilutions can be complex and tedious. Manually diluting samples can also cause sample contamination.
Standard addition is a calibration method that can replace the conventional standard curve calibration method to help eliminate chemical and physical interferences. Manually preparing standard additions is time-consuming and laborious due to the need to prepare multiple solutions for each sample, with variable amounts of known concentrations of the analyte.
The Agilent Sample Introduction Pump System (SIPS) accessory provides automation for flame AA analysis, increasing sample throughput, simplifying sample preparation and instrument operation. The accessory is available in a single pump version (SIPS 10) and a dual pump version (SIPS 20). The SIPS 10 enables automatic preparation of standard solutions from a single standard solution and auto dilution of over-range samples. The SIPS 20 also automates the preparation of standard additions and spikes (for spike recovery meaturements) and can add matrix modifiers and Internal standards.

应用 QuEChERS 方法结合 Agilent 7000 系列三重四极杆气质联用仪测定甜菜中 的多农药残留
本文介绍了一种用于分析甜菜中 267 种农药的简便、高通量方法。该方法将 QuEChERS 样品前处理方法与 Agilent 7000 系列三重四极杆气质联用系统相结合,并通过基质匹配标样校准进行定量,以降低基质干扰引起的定量偏差。结果表明,该方法在 2–200 μg/kg 的基质加标浓度范围内具有良好的线性关系。绝大部分目标农药化合物的定量限 (LOQ) 低至2 μg/kg,灵敏度高。加标回收率测试表明,在 2、5、10、100 和 200 μg/kg 的加标浓度下,大部分农药化合物的回收率在 80%–120% 的范围内 (n = 5) ,且相对标准偏差 (RSD)低于 10%。该方法适用于对甜菜中的多种农药残留进行常规分析。
