Title: Data processing apparatus for chromatographic mass spectrometer
Inventor: SHIMOMURA MANABU
IPC: G01N30/86
Filed: 1990-03-23
Abstract: PURPOSE:To make analysis of the results of mass spectrometry easy by assigning proper ions automatically to each peak of the all ion chromatographic and drawing the peak for each ion. CONSTITUTION:Passing an interface 2, an output of an ion detector of a chromatographic mass spectrometer 1 is taken in a CPU which processes the data and stored in an inside memory 3. An outside memory 4 is a library in which data of mass spectrum of various kinds of substances is stored. The CPU carry out peak-detection from the data of the all ion chromatogram taken in the memory 3. According to the time of the center of the peak, each mass spectrum data corresponding to the time is successively read out of the memory 3. Then, the data is collated with the data in the memory 4 and a parent ion mass which agrees to the data most is assigned and its peak intensity is read out. The CPU then processes the data and each peak intensity for each assigned ion having the mass is recorded in a printer 5. Differences between samples are thus analyzed well and analysis of the mass spectrum becomes easy.

Abstract: PURPOSE: To reduce the coil resistance by a method wherein the combined force of the electromagnetic force generating in an electromagnetic plunger through the input current for an electromagnetic coil and the compressed coil spring repulsive force is opposed to the fluid pressure acting on the needle valve to increase the coil coolling effect.  
     CONSTITUTION: Assuming that the compressive strength through the pressure governing spring 24 of the compression coil spring 22 is Δx, the coil current for the driving coil 26 is i 2  and K is a comparison constant, the force F 4  pressing the needle valve 18 against the valve seat 15 is F 4 =F 2 -F 3 =kΔx+G-K 3 i 2   2 . Since the return pressure P 2  is evidently in proportion to F 4 , and presuming that K 4  is a comperative constant, P 2 =K 4 F 4 , i.e. P 2 =K 4 (kΔx+G)-K 4 K 3 i 2   2  so that the coil current i 2  and the return pressure P 2  is relted as shown in the drawing. The electromagnetic pressure relieving valve according to the present invention increases the relief fluid quantity passing through the valve together with the increased coil currnt i 2  thus increasing the coil cooling effect so that the coil resistance increase is checked the current value is extremely low held down.
