Low-cost Microfluidic Emitters for Nano-electrospray Ionization-mass Spectrometry
نویسندگان
چکیده
We report a new microfluidic emitter for nano-electrospray ionization mass spectrometry (nanoESI-MS), made from polyimide tape. In contrast to the conventional pulled glass capillary emitters typically used for nanoESI-MS, these new polyimide emitters are simple and inexpensive to make, and are disposable after a single use. Thus, sample contamination and clogging are never a problem when analyzing different samples. The new emitters have comparable performance to pulled glass emitters, and are applicable to a variety to sample types and volumes, with the advantages of low cost, ease of use, and disposability.
