Abstract: A pressure transmitter and a method for enhancing the performance of the pressure transmitter, can involve obtaining pressure values from a pressure transmitter during a period of time in which pressure is not present in the process of a process control system, determining a long-term drift based on the obtained pressure values during the period of time in which pressure is not present in the process, and correcting the long-term drift by offsetting the amount of pressure measurement by the pressure transmitter to improve the measurement accuracy of the pressure transmitter. The long-term drift can be further determined with temperature measurements made by the pressure transmitter. In addition, a zero correction function may be performed to remove drift.

Abstract: The present invention is an improved apparatus and method for mass spectrometry using a dual ion trapping system. In a preferred embodiment of the present invention, three “linear” multipoles are combined to create a dual linear ion trap system for trapping, analyzing, fragmenting and transmitting parent and fragment ions to a mass analyzer—preferably a TOF mass analyzer. The dual ion trap according to the present invention includes two linear ion traps, one positioned before an analytic quadrupole and one after the analytic multipole. Both linear ion traps are multipoles composed of any desired number of rods—i.e. the traps are quadrupoles, pentapoles, hexapoles, octapoles, etc. Such arrangement enables one to maintain a high “duty cycle” while avoiding “memory effects” and also reduces the power consumed in operating the analyzing quadrupole.
