USP 代码 ：该柱符合 USP G5 要求。
相：
USP 代码 ：该柱符合 USP G5 要求。
相：
- 非键合
- 聚（双氰丙基硅氧烷）
- 常温至 250°C（等温或程序升温）
SP®-2340 is a cyanopropylsiloxane stationary phase, and has high polarity and temperature resistance.
Application
Capillary column coated with SP®-2340 stationary phase may be used in gas chromatographic analysis and separation of cis/trans isomeric fatty acids.
Other Notes
We offer a variety of chromatography accessories including analytical syringes
