一般描述
样品基质相容性 ：油类
- 含有 LC-Florisil ®（上层）和 Z-Sep/C18（下层）SPE 吸附剂的双层 SPE，通过 PE 熔块分离。
- 开发用于在分析来自石油基质的非极性持久性有机污染物 (POP) 时提供优越的清理。
- 脂肪基质优先保留在滤芯中，而非极性 POP 用乙腈清洗。
这种多床固相萃取 (SPE) 小柱设计用于从橄榄油和玉米油等食用油基质中提取非极性持久性有机污染物 (POP)，特别是重和轻的多环芳烃 (PAHs)。当使用乙腈清洗多环芳烃时，脂肪基质优先保留在滤芯中。所得浸提液适用于 GC-MS 或 HPLC-FLD 分析。SPE 小柱的顶层由 Florisil ® 组成，这是一种极性吸附介质，可与极性官能团（如酸和醇）相互作用。底层由 Discovery ® DSC-18 和 Z-Sep 吸附剂组成。C18 通过疏水作用结合脂肪基质。Z-Sep 是一种氧化锆涂层二氧化硅，作为 Lewis 酸，与脂肪酸、单甘油酯和甘油二酯中的 OH 和 COOH 基团内的氧相互作用。

How to Find a Lot/Batch Number for COA
Lot and Batch Numbers can be found on a product's label following the words 'Lot' or 'Batch'.
Aldrich Products
For a lot number such as TO09019TO, enter it as 09019TO (without the first two letters 'TO').
For a lot number with a filling-code such as 05427ES-021, enter it as 05427ES (without the filling-code '-021').
For a lot number with a filling-code such as STBB0728K9, enter it as STBB0728 without the filling-code 'K9'.
Not Finding What You Are Looking For?
In some cases, a COA may not be available online. If your search was unable to find the COA you can request one.
