Abstract: A photoionization detector (PID) lamp assembly and method are disclosed. The PID lamp assembly comprises a cap defining a lamp chamber within and the cap having a step aperture. Further, a crystal window is sealed over the cap and is configured to allow the passing of ultraviolet (UV) light. Further, a capillary tube is sealed to the cap via the step aperture of the cap. Thereafter, a pair of annular grooves are formed on the cap to install a pair of driving pads on the cap.

Abstract: Embodiments are provided for ultraviolet lamps for use in photoionization detectors and methods of manufacturing same. An example method of manufacturing an ultraviolet lamp includes providing a glass tube, the glass tube defining a first end; applying a mixed powder coating composition onto an edge surface of the first end of the glass tube, the mixed powder coating composition comprising indium powder and glass powder; applying a glass powder coating composition over the mixed powder coating composition; attaching a crystal window to the edge surface of the first end of the glass tube; and heating the glass tube and the crystal window to seal the crystal window to the glass tube.

Abstract: The invention provides a method for producing high-quality lard or beef tallow with low cholesterol content. The method of the invention uses enzyme hydrolysis, centrifugation separation and homogenization-assisted embedding technique to obtain high-quality lard or beef tallow with low cholesterol levels. The method uses aqueous enzymatic extraction (AEE) techniques to separate lard or beef tallow from the raw material of pork or beef fat, and uses the homogenization-assisted embedding technique to remove cholesterol from the lard and beef tallow products. The method of the invention produces high quality lard with good oxidative stability at a high yield and can meet the Chinese national standard for first grade lard. The lard of the invention needs no further degumming process, eliminating the tedious refinery steps.

Abstract: A polishing method includes: mounting a wafer on a fixed abrasive polishing pad located on a polishing platen; delivering a polishing slurry to the fixed abrasive polishing pad to polish the wafer; and adsorbing abrasive particles generated during the polishing process with an electrode. The electrode has a polarity opposite to a polarity of charges of the abrasive particles. A polishing device includes a polishing platen, a fixed abrasive polishing pad, a slurry pipeline and a polarity changer having an electrode. Therefore, the abrasive particles generated during the polishing process are removed, which prevents the wafer from being scratched, thereby increasing wafer yield and improving efficiency.
