一般描述
Empore 膜固相萃取技术包含紧密地装入惰性 PTFE 原纤维中的固相萃取颗粒（90% 固相萃取颗粒 : 10% PTFE，重量比）。固相萃取膜的制造工艺能够形成均匀的高密度萃取介质，该介质相对于传统的吸附剂/填充床固相萃取产品具有明显的优势。Empore 固相萃取技术可以提供比传统填充床产品密度更大、更均匀的萃取床，从而使床重量更轻、分析物到空隙扩散的路径更短，并且萃取效率更高。
Empore 系列固相萃取圆片是用于萃取大量水性样品的最完整的固相萃取圆片产品。该产品系列包括经过时间考验的试验 C18 以及独特的相化学性质（例如碳和高极性油脂圆片）。该圆片是环境分析的理想选择，此类分析的样品量通常为 1L，并是 LLE 的高效替代方案。

省时省钱：
- 降低固相萃取床质量 = 减少固相萃取溶剂和洗脱体积
- 使固相萃取洗脱液蒸发时间最短
- 能够直接注入固相萃取洗脱液
- 致密均匀的萃取介质 = 无固相萃取通道和空隙效应
- 高效的传质动力使流速更快
- 消除固相萃取细粒，延长色谱柱和仪器的使用寿命
应用
- Determination of diphenylarsinic acid, phenylarsonic acid and inorganic arsenic in drinking water: This study utilizes Empore SPE Disks for the simultaneous separation and preconcentration of toxic compounds in drinking water, highlighting the disks′ application in environmental safety and public health (Hagiwara et al., 2013).
- Monitoring of ecotoxicological hazard potential by polar organic micropollutants: The research emphasizes the utility of SPE disks in the environmental monitoring of micropollutants, contributing significantly to the assessment of water quality and ecological risks (Escher et al., 2008).
- Determination of commonly used polar herbicides in agricultural drainage waters: Demonstrates the efficiency of SPE Disks in analyzing herbicide residues in agricultural runoff, providing insights into pollution control and chemical residue management (Tran et al., 2007).
- Stability of pesticides on solid-phase extraction disks: Explores the stability of various pesticides on SPE disks under different conditions, proving the disks′ reliability for sample storage and analysis in multi-environmental studies (Cobb et al., 2006).
其他说明
开发用于从水样和土壤提取物中混合提取极性和非极性分析物。 为具有极性官能团的分析物提供独特的选择性。 由于该相含有磺酸官能团，二次SCX相互作用可发生在含有胺官能团的碱性化合物上。
- 爆炸残留物（HDX、RDX）
