Abstract: The present invention is directed to a method for determining the presence of a residue on or within a fingerprint using matrix-assisted mass spectrometric techniques. The matrix-assisted mass spectrometric technique can be selected from Matrix-Assisted Laser Desorption/Ionization Mass Spectrometry Time-Of-Flight Mass Spectrometry (MALDI-TOF-MS) and/or Surface Assisted Laser Desorption/Ionisation Time-Of-Flight Mass Spectrometry (SALDI-TOF-MS).

Abstract: In order to form an ionization and/or drift area, the ion mobility spectrometer (IMS) has two opposing wall elements (1, 2) which are joined to each other by a spacer and provided with planar, parallel gas conducting surfaces that have opposing conductor structures (4) which produce a drift field (E-field). The ratio between the distance (d) separating the gas conducting wall surfaces and the field-generating width (b) of the conductor structure perpendicular to the direction of drift (x) is less than 1/2 and preferably 1/3 - 1/10.

Abstract: The invention pertains to a method for fiuorometrically monitoring a Clean-In-Place ('CIP') system and for fiuorometrically monitoring the dosage of chemical added to the CIP system. Monitoring of the said CIP system can be based upon fluormetrically monitoring the fluorescent tracer, chemical or both, which are added to the CIP system.

Abstract: A method and system of separating species in a mixture by conversion to gas phase ions, separation based on mass/charge ratio and/or mobility, and collection of the separated ions. The system (18) includes a multiplexed electrospray ion source (19) for producing streams of ionized species (23), which are fed to a linear ion trap (24) for separation. The separated species pass through a focusing lens (29) for deposition on a spot (14) on substrate.

Abstract: A distance of flight (DOF) approach to mass spectroscopy in which the resolution among the various ion masses is accomplished in space rather than time. A separate detector is associated with each ion mass resolution element. The DOF mass spectrometer can serve as one element in a tandem arrangement which has the capability to produce a full two-dimensional precursor/product spectrum for each bunch of ions extracted from the source. A "distance-of-flight" (DOF) mass analyzer is used in combination with time-of-flight (TOF) mass analysis for precursor and product dispersion. All the precursor ions can undergo a mass changing reaction simultaneously, while still retaining the essential information about the particular precursor m/z value from which each product m/z value emanated. Through the use of a two-dimensional detector, all the products ions from all the precursors can be detected for each batch of ions analyzed.

Abstract: There is provided an ion-mobility spectrometer. This apparatus includes the following configuration components: An ion source (1) for generating first ions, a first drift unit (L1) for separating the first ions by flight drift times, an ion dissociation unit (Lg) for generating second ions by dissociating the first ions separated, and a second drift unit (L2) for separating the second ions by flight drift times. Moreover, the first drift unit (L1), the ion dissociation unit (Lg), and the second drift unit (L2) are located inside a chamber whose pressure is set at 10 mTorr or higher. This apparatus allows execution of low-cost and high-resolving-power ion separation and detection.
