Case Study: High Sensitivity Gel Permeation Chromatography for Agrochemical Analysis

In 2015, Syngenta, a major agricultural company in the US, made a decision to acquire an OMNISEC Gel Permeation Chromatography (GPC) system from Malvern Panalytical.

Syngenta的高级分析化学家Kirt Durand博士描述了决策过程，公司如何使用Omnisec GPC系统以及他与Malvern Panalytical合作的经验。

“We already have many Malvern Panalytical systems in our company, primarily for particle sizing but also rheology, so when it came to upgrading our GPC capability we were keen to take a look at OMNISEC,”says Dr Kirt Durand.

GPC系统是一项重大投资，我们从以前的经验中知道，我们可以依靠Malvern Allytical来获得真正的出色支持。OmniSec是一种很棒的工具，但通过购买过程，Malvern Panalytication的服务确实使该公司与其他供应商区分开来。在整个购买过程中，该服务一直保持一致，我们有信心做出了正确的选择。

先正达参与了各种农业化学物质的制造，包括除草剂，杀菌剂，农药。该公司将许多农业化学物质作为液体悬浮液制定。这些制剂的聚合物成分包括抗泡沫剂；缓冲剂；流变/粘度修饰符；润湿剂和分散剂。在这些聚合物成分中保持一致性至关重要，以确保总体产品质量控制。

“We’re a central analytical facility for the company,”杜兰德博士说“因此，我们看到许多不同的样本并应用了广泛的分析技术。GPC对于我们分析的聚合物组件至关重要，以确定分子量，分子量分布和存在的材料量。”

We use it routinely to confirm that all the components in a formulation are in suspension, in the concentrations that they should be, most especially when we have a 2 High sensitivity gel permeation chromatography for agrochemical analysis manufacturing issue, when we’re investigating an out of specification product, for example, or an unforeseen interaction between a product and its packaging.
