*For the analysis of high dissolved solids and organics the sample compartment

door must remain open while the instrument is in operation.

这是操作手册里的一段话，为什么高盐和有机的样品要把门给打开？

把门打开了，温度相对低点，溶解度变小，可能会有晶体析出，还是溶剂没那么容易挥发？

为什么温度低有利于有机和高盐样品进样？

我用过5300dv和7300dv，门都是打开着，样品时金属，塑胶，纺织品等？

pe的版友，你们又是怎样的？

还有一句话

To successfully determine torch position always duplicate the conditions you will
be running your samples. For example, have the sample compartment door closed
when running aqueous samples and open when running organic solutions.

水性关门，有机开门，何解。。。。
