5) cryofocus
冷阱
1.
A method combining solid phase microextraction (SPME) with cryofocus technique was developed for the compound-specific carbon isotope analysis of volatile organic compounds in aqueous phase.
将固相微萃取 (SPME)技术与冷阱富集系统相结合 ,对水体中痕量挥发性有机物进行了单体碳同位素分析 ,方法检测限较常规SPME提高了一个数量级。
2.
In this paper, we developed a method combining SPME with cryofocus technique for the compound-specific carbon isotope analysis of volatile organic compounds in aq.
采用固相微萃取 -冷阱富集GC -IRMS技术对水中痕量挥发性有机物进行了单体碳稳定同位素分析 ,样品经SPME萃取富集后在色谱进样口冷冻成形 ,样品多次进样得以累积从而满足了检测限的要求 。
6) Cold-trap
冷阱
1.
Cold-trap which is also called vapor-condenser in vacuum freezing dryer is mostly used to catch vapor that is sublimed from drying chamber.
真空冷冻干燥机中的冷阱主要是用来捕集从干燥室内升华出来的水蒸气,水蒸气流经冷阱后直接凝华成霜而被抽除,因此也称其为水汽凝结器。
2.
Under low temperature and low-pressure condition,water vapor directly becomes frost on cold-trap.
在真空冷冻干燥装置中,冷阱是用来捕集从物料中升华出来的水蒸汽的主要设备。
补充资料：冷凝
分子式：
CAS号：
性质：使热物体的温度降低而发生相变化的过程。通常指使气态物质经冷却而变成液态的过程。例如水蒸气冷凝而成水。通常有膜状冷凝和滴状冷凝两种。
