一般說明

SPE是一种层析方式，就像其他层析技术一样，控制流率是保持可重复提取的关键。不像其他的真空装备，Visprep系统含有具有专利的阀系统，使用旋转的，独立的，螺旋型的阀们，能够对经过每一个SPE管的流量精准控制。阀们安装在装备的每一个端口上。Visprep真空装备使你能够一次同时处理12（12端口版本）或24（24端口版本)个SPE样本。24端口版本的每个端口间距离比12端口版要小，所以建议购买前考虑好管子大小。
Visiprep DL（一次性连接管）真空固相萃取装置消除了在同一端口处理新样品时发生交叉污染的风险。该一次性连接管一端是聚丙烯内螺纹luer 接口可以直接连到 SPE 小柱上，另一端 PTFE 细管可以通过 SPE 装置的端口。这可确保与样品接触的所有固相萃取端口和控制阀的表面可在每次萃取后得到更换。

特點和優勢

  • 固相萃取端口中专利的螺旋式阀门用于精确的流量控制
  • 玻璃槽接触到溶剂时不会溶解、变模糊或褪色
  • 盖上带有支脚，当使用者将盖从固相萃取装置上取下时，可方便地放在工作台上
  • 螺旋式耐溶剂真空表和减压阀提供更好的密封和真空控制。阀门可与 1/4″ 英寸真空管连接。
  • PP 收集容器架可容纳自动进样器样品瓶；小型闪烁样品瓶（推荐 22.75mm 外径）；10 和 16mm 试管；以及 1、2、5 和 10mL 容量瓶。可为 12 端口的型号选配用于 20mL 闪烁样品瓶的板。
按100只一次性衬垫（货号57059）进行提供。

Toxins, 11(6) (2019-06-05)
Mycotoxins are secondary metabolites, produced by fungi of genera Aspergillus, Penicillium and Fusarium (among others), which produce adverse health effects on humans and animals (carcinogenic, teratogenic and immunosuppressive). In addition, mycotoxins negatively affect the productive parameters of livestock (e.g., weight

Improved Recoveries and Lower Background for GC/MS/MS and LC/MS/MS Analysis of Pesticides in Green Tea

A procedure for cleanup of green tea extracts provides low background and allowed for the analysis of more pesticides at lower levels than QuEChERS. Uses less solvents and no toluene.

Analysis of Pesticide Residues in Ginger Powder Using QuEChERS Extraction and Clean-up with a Novel Dual Layer SPE Cartridge

The odor and pungency of ginger is due to the presence of terpenes, gingerols and shogaols. These compounds contribute to the highly complex matrix of ginger, which subsequently presents a challenge in low level analyses of contaminants. A novel 2-layer SPE cartridge efficiently reduces background for pesticide determination.
