A system and method for introducing and analyzing a sample containing an analyte using an ion mobility spectrometer are described. The system includes a temperature module for adjusting the temperature of the sample according to temperature instructions received, and a split ratio module for adjusting the split ratio according to split ratio instructions received. An ion mobility analyzer determines an ion mobility of the analyte. The ion mobility analyzer collects a plasmagram of the analyte to identify and quantitate the analyte.

Method and system for introducing an analyte into an ion mobility spectrometer

A system and method for establishing the cleanliness of a device by performing a test is described. The system includes an ion mobility spectrometer to measure target signal strengths, and to measure n&#x2267;1 test signal strengths of a device sample. The system also includes a statistics module to obtain a value of a statistical confidence-level parameter that is associated with a particular confidence level, and a pass range module to obtain a pass range of signal strengths from the value of the statistical confidence-level parameter and the ntarget signal strengths. The system also includes an averaging module to obtain an average test signal strength from the ntest signal strengths, and a results module to determine that the device passes the test, indicating that the device is significantly clean to within the particular confidence level, if the average test signal strength lies in the pass range.

A fiber having increased cut resistance is made from a fiber-forming polymer and a hard filler having a Mohs Hardness Value greater than about 3. The filler is included in an amount of about 0.05% to about 20% by weight. In preferred embodiments, the fiber-forming polymer is poly(ethylene terephthalate) or a liquid crystalline polyester comprising monomer units derived from 6-hydroxy-2-naphthoic acid and 4-hydroxybenzoic acid. Preferred fillers include tungsten and alumina.

Filled cut-resistant fiber

A sheet made of a polyester which includes monomer units of terephthaloyl moieties, ethylene glycol moieties and isosorbide moieties is described. The polyester has an inherent viscosity of at least about 0.35 dL/g when measured as a 1% (weight/volume) solution of said polyester in o-chlorophenol at a temperature of 25.degree. C. The present invention also relates to a method of making the polyester sheet described above and a method of thermoforming the sheet into articles.

Cut resistant non-woven fabrics

Cut-resistant fiber containing a hard filler

Composite yarns having exceptional cut resistance are made by combining at least two different kinds of fiber, as follows: (a) a high modulus fiber having a modulus greater than about 200 gpd as measured by ASTM Test Method D-3822; and (b) a particle-filled fiber, which is made from a semi-crystalline polymer, such as poly(ethylene terephthalate), and hard particles having a Mohs Hardness Value greater than about 3.

Composite yarns having high cut resistance for severe service

An extrusion blow molding process for a heat-treated, liquid crystalline polymer is provided. By the process, molten polymer having improved melt strength, is vertically extruded downward into space through a parison-forming, annular gap. Sag resistant parisons are formed. Beneficially, the parisons may be formed periodically. Advantageously, large-sized parts or structures may be produced.
