Introduction: Detection of Cryptosporidium and Giardia parasites in water samples is usually performed by US Environmental Protection Agency 1623 method. Nevertheless, the USEPA1623 method still need improvement, to prevent and control the water borne parasitic disease. Therefore, we undertook the present study. Materials and methods: Totally 48 surface water samples were collected. Four sampl...

Rationale Ion mobility spectrometry (IMS) instruments are typically equipped with atmospheric pressure chemical ionization (APCI) sources operated at ambient pressure. However, classical APCI-IMS suffers from a limited yield for nonpolar substances low proton affinity (PA). This is mainly due to ion clustering processes, especially those that involve water molecules, inhibiting the of these sub...

Multidimensional ion mobility spectrometry (IMS-IMS and IMS-IMS-IMS) techniques have been combined with mass spectrometry (MS) and investigated as a means of generating and separating peptide and protein fragment ions. When fragments are generated inside a drift tube and then dispersed by IMS prior to MS analysis, it is possible to observe many features that are not apparent from MS analysis al...
