产品简介
该产品具有五路独立的控制区域:柱箱、进样器、检测器、热导池、辅助器。 可实现五阶程序升温,具有柱箱自动降温即后开门功能,实现快速冷却。 仪器可进行填充柱分析或毛细管柱分析,可实现多种进样方式。
主要特点

(一)全新设计的GC112A微机温度控制系统,采用了国际先进的控制技术。控温精度高(优于±0.05℃)可靠性和抗干扰性能优越。

(二)健盘设定各种控制和使用参数(包括检测器操作参数),机内具有自诊断、断电保护、文件存储及调用、极限温度设定等功能。可准确显示各路温控设定值、实际值、TCD桥流;FID放大器灵敏度、保留和分析时间等。

(三)且有五路独立的控制区域:柱箱、进样器、检测器、热导池、辅助器。

(四)该产品可实现五阶程序升温,具有柱箱自动降温即后开门功能,实现快速冷却。

(五)仪器基型配有双氢火焰离子化检测器(FID),可选配GC112A-TCD热导检测器、气体进样阀、转化炉等附件,可同时安装二种检测器(FID和TCD),且检测器灵敏度高(如FID的测试结果:

    Mt≤1×10-11g/s),稳定时间短,喷口的清洗和安装方便。

(六)该产品可容易方便地安装填充柱和毛细管柱(0.53大口径柱或小口径柱),且附件中有全套的毛细管分流进样接头和尾吹接头(不需另外付费)。可选配分流/不分流进样器、0.53mm大口径毛细管柱直接进样器。

(七)仪器可进行填充柱分析或毛细管柱分析,可实现多种进样方式。

填充柱:柱上进样、瞬时汽化进样、气体进样;毛细管柱:分流进样、不分流进样、0.53大口径柱直接进样。

(八)仪器具有双气路、双进样器、双填充柱系统结构,可有效地实时抑制基线波动及漂移,适合于程序升温分析。精确的刻度式气路控制阀件,具有高重现性和稳定性。

(九)仪器具有自动开启和自动关闭温度控制系统、数据永久保存、文件存储及调用、过温保护等先进功能。

(十)大容量柱箱(300mm×280mm×270mm)方便安装毛细管柱和双填充柱;内藏式加热丝结构,更有利于石英毛细管柱分析。

(十一)采用CAD设计技术,机械零件是在进口立式HITACHI数控加工中心和AMADA数控冲床等先进设备上实施加工,机械精度高,结构可靠,且外型美观,极富人性化。
