摘要:
A method for introducing standard gas into a sample vessel is generally disclosed comprising providing a vessel containing a sample gas and a receptacle with a vessel port, such as sampling needle, pressurizing the vessel with a carrier gas, and introducing a volume of standard gas into the flow path of the carrier gas being used to pressurize the vessel when the vessel port of the receptacle is located within the vessel. In some embodiments, a rotary valve is loaded with the standard gas, and the valve is brought into fluid communication with the flow path of the carrier gas when the vessel port is within the vessel.

The methods described herein can be used, e.g., for detecting at least two target molecules in a sample (e.g., a single sample). Exemplary methods include using a target-specific switch probe attached to a substrate and using zip codes to associate holographically encoded particles with a target-specific probe.

Methods and systems for automatically locating and identifying labware using radiofrequency identification (RFID) tags are described herein. The methods and systems include a plurality of RFID tags (pre-programmed with unique data codes) that are associated with labware (or labware holders). For example, the RFID tags can be embedded within the locating pegs of the labware (or labware holders). The methods and systems also include a plurality of RFID tag readers that mount near known locations of an instrument deck which receives the labware. The RFID tag readers automatically scan for the presence of RFID tags such that when a piece of labware is added to the instrument deck, and then report to a processing device the specific known location on deck where each tag was found, as well as the unique data code of each tag. Using this information, the methods and systems determine one or more of the location, orientation, and identity of the received labware.

The invention provides methods for detecting and isolating phosphomolecules using phosphoaffinity materials that comprise a hydrated metal oxide. In an embodiment, a method for detecting a phosphomolecule in a sample involves (a) contacting a sample with a phosphoaffinity material comprising a hydrated metal oxide, under conditions wherein a phosphomolecule is capable of binding to the phosphoaffinity material to form a phosphomolecule-phosphoaffinity material complex, and (b) detecting formation of a phosphomolecule-phosphoaffinity material complex, thereby detecting a phosphomolecule in the sample. In another embodiment, a method for isolating a phosphomolecule from a sample involves (a) contacting a sample with a phosphoaffinity material comprising a hydrated metal oxide, under conditions wherein a phosphomolecule is capable of binding to the phosphoaffinity material to form a phosphomolecule-phosphoaffinity material complex, wherein the hydrated metal oxide comprises yttrium, and (b) separating the phosphomolecule-phosphoaffinity material complex from the sample, thereby isolating the phosphomolecule from the sample.
