A mass spectrometer is disclosed comprising a sampling cone (3) and a cone-gas cone (4) wherein, in use, sulphur hexa fluoride (‘SF6’) is supplied as a cone gas (5) to the annulus between the cone-gas cone (4) and the sampling cone (3) in order to improve the transmission of high molecular mass ions passing through the sampling cone (3) into and through subsequent stages of the mass spectrometer.
摘要:
A neutral automatic dishwashing detergent composition comprising an acidifying particle comprising an aminocarboxylic builder wherein the acidifying particle has a low hygroscopicity, a cake strength of at most 20N and a pH of from about 2 to about 6 as measured in 1% aqueous solution at 20° C.
摘要:
An intervertebral fusion device for promoting fusion of first and second vertebrae comprises first and second endplate modules. Each endplate module includes an outer surface adapted to interface with vertebral bone and an opposite inner surface. The endplate modules further include an attachment feature. A central module is adapted to extend between the first and second endplate modules and is further adapted for connection with the attachment feature. A through passage extends through the outer and inner surfaces of the each of the first and second endplates and through the central module.

To display a news feed in a social network environment, a social networking system generates news items regarding activities associated with a user of a social network environment. The social networking system may also attach an informational link associated with at least one of the activities to at least one of the news items, limit access to the news items to a predetermined set of viewers, and assign an order to the news items. The news items may be displayed in the assigned order to at least one viewing user of the predetermined set of viewers, and the number of news items displayed may be dynamically limited.
摘要:
A particle comprising an aminocarboxylic builder and sulphate or citrate wherein the aminocarboxylic builder and the sulphate or citrate are present in a weight ratio of from about 6:1 to about 1:1.
摘要:
A method of chemical separation includes dispensing a sample from a sample pumping system, pumping a solvent from a solvent gradient pumping system to elute the dispensed sample through a separation column, identifying an analyte of interest in the eluting sample, and pumping a solvent from the sample pumping system for peak parking of the analyte in the separation column.
