Abstract: When mounting a second assembly 36 to a first assembly 35 that is fixed to a main body, the second assembly 36 engages a second connection element 54 of a non-rotation unit 361 of the second assembly 36 with a first connection element 354 of the first assembly 35. A rotating part 362 is mounted on the first assembly 35 when the rotation unit 362 is rotated. Therefore, an operator can carry out positioning for the second assembly 36 by connecting the second connection element 54 of the second assembly 36 with the first connection element 354 of the first assembly 35. The second assembly 36 can be smoothly mounted on the first assembly 35 that is fixed to the main body. The second connection element 54 of the non-rotation unit 361 connects with the first connection element 354 of the first assembly 35, so that the non-rotation unit 361 is prevented from rotating together with the rotation unit 362 during use and the assemblies that contact the non-rotation unit 361 are protected from damage.

Abstract: Device for sampling a liquid in a tube by means of a hollow needle (10) passing through the closing cap (12) of the tube (14), means (18, 20) with rack and toothed wheel being provided to oppose the rising of the tube (14) when the needle is extracted from the cap (12).

Abstract: Preparation methods for introducing liquid samples to gas analysis instruments include 1) complete evaporation of a liquid sample in a sample chamber, and 2) allowing the sample vapor in the sample chamber to equilibrate for a predetermined time. An inert carrier gas (e.g., dry nitrogen or zero air) is also admitted to the sample chamber. After equilibration, the sample vapor is admitted as a conditioned sample to an analysis instrument. Preferably, the predetermined equilibration time is sufficiently long that the sample vapor in the sample chamber becomes substantially homogeneous with respect to both concentration and isotopic ratio. Vapor derived from a liquid calibration standard in this manner can be employed as an accurate gas-phase calibration reference.

Abstract: Provided is a micro electro mechanical systems (MEMS) device for use with an elongate structure. The MEMS device includes a generally planar substrate, a device wall layer formed upon the substrate, a septum cavity formed in the device wall layer, a channel formed in the device wall layer in fluid communication with the septum cavity, and a septum element disposed in the septum cavity. The septum element is formed of a viscoelastic material. The septum element defines a septum entry surface and a septum exit surface with the septum exit surface being exposed to the channel and disposed between the septum entry surface and the channel. The septum element is without any openings formed through the septum element extending between the septum entry and exit surfaces. Methods of manufacturing and interacting with the MEMS device are also provided.

Abstract: The invention relates to a coupling system that can particularly be applied for interfacing a consumable component with a sample chamber to a laboratory instrument for processing a sample fluid. The coupling system comprises a female interface module (10) integrated into the consumable component that has an elastic sealing component (12) with a preformed channel (12a). Moreover, it comprises a male interface module (20) integrated into the instrument and comprising a hollow needle (23) fixed in a first section (22a) of a bush (22), wherein the flexible free end of said needle (23) is partially surrounded by a second section (22b) of the bush that limits the lateral movement of the needle. The diameter of the channel in the sealing component (12) is preferably smaller than the diameter (d) of the needle (23), thus providing an airtight connection and a self-cleaning effect.

Abstract: A sample processing/injection device for liquid chromatography comprises a septum at one end of the device, a processing chamber and injection needle disposed on a second end of the device. A fluid sample is transferred into the device by a transfer needle penetrating the septum of the device. The sample device may be positioned to a receiving component such as an injection valve of an instrument by movement of the transfer needle. The sample is injected into the receiving component through the injection needle of the sample processing/injection device through motive pressure supplied by the transfer needle. The sample processing/injection device reduces sampling steps and improves automation by performing sample processing and injection with a single device.

Abstract: The present invention is directed to an enhanced sampling device, herein referred to as an ESD, for enhancing the collection efficiency of the SPME method by enhancing the flow of the analytes onto the sampling fiber. The ESD includes a tubular main body, used for a sampling shroud, which directs a flow of analytes to contact the fiber during collection. One end of the main body is open and faces the sample, allowing analytes to flow into the ESD and contact the fiber. A second piece of tubing branches from the other end of the main body and becomes an outlet port, possibly leading to a pump. The ESD permits more rapid transport and absorption of the analytes to the fiber for collection.

The instrument assemblies can include a septum housing assembly coupled to an analysis chamber interface with the interface including a valve and a cam rotatably mounted to the septum housing assembly and/or coupled to the valve. Analysis methods are also provided that can include introducing a sample to an instrument through both a sample introduction port and a valve coupled to the sample introduction port, and, after introducing the sample, closing the valve to seal the sample introduction port from a remainder of the instrument, with the remainder of the instrument being configured to analyze the sample after the introducing through the sample introduction port.

Abstract: Apparatus and methods for supplying a portion of a fluid stream and, alternately, a fluid of known composition and concentration to an analyzer are provided. The fluid stream is directed through a series of connected chambers formed in an integral housing. A sampling needle has an inlet in one of the chambers and an outlet in fluid communication with the analyzer. When desired, a tube or vial containing a known fluid may be inserted into a chamber containing the sampling needle, so that the known fluid will be supplied to the analyzer. A second needle provides ventilation to the vial to prevent the formation of a vacuum as the known fluid is drained from the vial.
