固相微萃取金属合金纤维组件

The SPME metal alloy fiber assemblies are manufactured with a flexible metal alloy used in the needle, plunger, and fiber core. The new metal alloy design includes a thicker, flexible plunger that is much less likely to kink or break, and helps to reinforce the needle especially when used in an auto-sampler with a sample agitator. Since the needle is more flexible and has a thinner wall than the standard stainless steel needle, a bevel has been placed on the needle to help it pierce septa materials more easily. As a result of this thinner needle wall and beveled tip, septa coring will occur more frequently requiring the use of the Merlin Microseal or similar septum-less sealing system. The alloy used in the metal fiber assemblies does not contain any iron and is more inert than stainless steel.
