Title: Bandpass reactive collision cell
Inventor: BARANOV VLADIMIR I
IPC: H01J49/42
Filed: 1998-06-02
Abstract: A method of reducing isobaric interferences by transmitting ions from an ion source through an ion transmission device, typically a quadrupole collision cell, and then into an analyzing mass spectrometer, in which the collision cell is operated with a pass band which rejects intermediate ions which would otherwise tend to react to form isobaric interferences. Preferably ammonia is used as a reaction gas in the collision cell. Depending on the chemistry involved, the collision cell may be operated to set the low mass cutoff at an appropriate level, or more usually, the pass band will have both high and low mass cutoffs determined by applying both RF and DC to the collision cell. The collision cell may also be operated with a pass band to transmit ions into a time-of-flight (TOF) mass spectrometer, thus limiting the mass range of ions entering the TOF and thereby improving the duty cycle of the TOF.

IPC: B01D71/34
Filed: 1998-07-23
Abstract: Oils, extracted from vegetables and animal tissue contain impurities such as waxes, that can be removed by filtration. During filtration the impurities stick to the membranes, which causes a reduction in flux. The initial flux can be reached again by regularly cleaning the membranes by applying the steps of:  (a) backblowing with gas, (b) backflushing with edible oil, (c) treating the membranes with alkaline material. The cleaning method is in particular suitable for cleaning microfilters having an average pore diameter of 0.5-5 µm, that are used in an oil refining process.
