International Classification:

G06F 11/00

US Classification:

714048000

Abstract:

A method and system for providing customer service information provide a central database containing software modules for tasks and services and configurations for the modules. Information is received specifying a procedure to be carried out. Software modules relating to tasks forming part of the procedure are invoked, and the information indicative of appropriate configurations for the specified procedure is passed to the software modules. The software modules access the configurations, and instantiate operational tasks applying the configurations. The operational tasks are consolidated into an operational procedure, and the operational procedure is provided to an operative.

International Classification:

G01N 30/16
G01N 30/86

Abstract:

The present invention contemplates a variety of improved techniques including an injection module pairable with an injection port of a gas chromatography device. The injection module can include a cylindrical body, a cap with permeable membrane, a first reservoir for a sample, and a second reservoir for a volume of solvent. An internal membrane can be disposed between the first reservoir and the second reservoir. The injection module can include a circular plunger creating a seal with an inner surface of the cylindrical body of the injection module and configured to expel the sample and solvent by gliding along the inner surface of the cylindrical body. A server can monitor analytes detected by the gas chromatography device and generate recommendations for a user of the gas chromatography device.
