Chromium is a common harmful pollutant with high toxicity and low bearing capacity of soil and water. Excellent salinity resistance, a wide pH range, and high regeneration capacity were essential for qualified adsorbents used in removing hexavalent c

A simple direct flow modulator has been constructed and evaluated. This modulator employs a tee to connect the primary and secondary columns so that a negative pulsed flow can be introduced through the third leg of the connector into the joint betwee

A valve modulator with a hold-release primary column flow method has been proposed. This method uses a valve plumbed so that the head and tail of the primary column are connected during the secondary separation, to reverse, slow down, and finally sto

A pulsed discharge ionization detector (PDHID) with multiple combined bias/collecting electrodes (MC-PDHID) has been developed. Unlike most ionization detector designs with only one collecting electrode, the MC-PDHID builds multiple electrodes inside

Nickel clad or nickel wired fused silica column bundles were constructed and evaluated. The nickel sheathing or wire functions not only as the heating element for direct resistive heat, but also as the temperature sensor, since nickel has a large res

This paper is a review of the research that has been performed on the development and applications of a non-radioactive electron-capture detector (ECD). The ionization in the ECD, normally supplied by a radioactive foil, is supplied by the electromag

A feedback dc bias voltage has been utilized to established a constant-current operation mode (cc-mode) for the pulsed discharge electron capture detector (PDECD). The feedback voltage is directly proportional to the concentration of analyte in the d

Various commercially available ultra-fast temperature programming approaches were integrated to silicon micromachined GC (micro-GC) for performance improvement assessment. The combined technique of micro-GC and ultra-fast temperature programming up t
