国家药典委于2024年7月26日发布了完善版的《0212药材和饮片检定通则标准草案公示稿》和《2341 农药残留量测定法标准草案公示稿》，引起了行业内的关注和重视。

新增11种中药材的36种限用农药清单。通则2341中农残测定方法也发生了很大变化。面对这样的变化与挑战，莱奥已建立整体解决方案，以助力相关机构及企业从容应对。

三、实验步骤概要

1、取粉末5g，加NaCl1g，加入乙腈50ml提取2次，合并提取液，减压浓缩至5~10ml，乙腈稀释至25ml。

2、根据标准中4.3固相萃取法（方式三）：量取浓缩后提取液2ml，用Purifier A48 48位正压固相萃取仪净化样本。

3、收集后的洗脱液，和架子一起转移至SmartVap AE 48位氮吹浓缩仪，浓缩近干，用乙腈复溶2ml，待上机。

2、批量大，效率高：样品量最大可兼容48批次，同时过柱及氮吹，节省实验时间。

3、固相兼容氮吹，无需转移：过柱后样品架可直接转移到Leowlab SmartVap AE 48位全自动氮吹浓缩仪，避免转移带来的损失。

4、涡旋斜吹技术：Leowlab SmartVap AE 48位全自动氮吹浓缩仪，采用斜吹技术，可更加快速，平和、防飞溅的基础上，很好的完成氮吹。

5、筛选氮吹针误差测试，保证平行性：Leowlab SmartVap AE 48位全自动氮吹浓缩仪的氮吹针经过针与针直接误差测试，层层筛选过，保证氮吹样品的平行性。

6、氮吹不跟随液面下降：Leowlab SmartVap AE 48位全自动氮吹浓缩仪不跟随液面下降，防止样品交叉污染。
