A system for separation of components of a natural gas product uses a first separation column to receive the natural gas product and to provide first stage components including a first component gas, uses a gas converter to provide second stage components that includes third component gas from at least a second component gas of such first stage components, and uses a second separation column to provide third stage components that includes the first component gas, the third component gas, and one or more additional carbon-based components provided in or over a period of time associated with the separation of the components of the natural gas product.

The present invention relates to a gas-liquid separator for a chromatography system, comprising: (a) a separating region having an inlet nozzle, a baffle unit and a gas distribution unit; (b) a dividing region having a liquid outlet; and (c) a gas discharge region having a gas outlet; wherein the separating region is connected to the dividing region by a separating opening and the distance of the inlet nozzle from the baffle unit is greater than the smallest longitudinal extension of the separating opening and the inlet nozzle is configured such that a gas-liquid stream directed through the inlet nozzle can act on the baffle unit.

The present invention further relates to a chromatography system comprising a separator according to the invention and to a chromatography method wherein the separator is used.

A method for analyzing light n-alkane components and carbon isotopes in deep and ultra-deep source rocks includes: (S1) subjecting a 5A molecular sieve column to aging; (S2) pyrolyzing a source rock; and allowing a pyrolysis product to enter the 5A molecular sieve column; where n-alkanes are adsorbed and retained by the 5A molecular sieve column; allowing an outflow to pass through a fractionation plate and an empty column or a weak polarity column to be discharged; and (S3) performing programmed heating such that the n-alkanes adsorbed on the 5A molecular sieve column are successively desorbed according to molecular weight, and then pass through the fractionation plate and the HP-5 or DB-5 column to enter a mass spectrometer for composition analysis or isotopic analysis. An analysis system is further provided.

A concentrator includes a casing, a separation membrane that sections an inner space of the casing to form a flow path in the casing, a first supplier that supplies a first liquid from a first position of the casing to the flow path such that the first liquid flows along the separation membrane in a first direction, a second supplier that supplies a second liquid from a second position of the casing to the flow path such that the second liquid flows along the separation membrane in a second direction opposite to the first direction, and a third supplier that supplies a third liquid including a target component having a size that does not allow permeation of the target component through the separation membrane from a third position of the casing to the flow path.

A nebulizer for a charged aerosol detection (CAD) system is disclosed. The nebulizer is provided with a spray emitter for generating a spray of droplets within a central region of a spray chamber. The central region is separated from an upper region by a horizontally projecting rib, which defines a passageway between the central and upper regions. The major direction of droplet travel within the upper region is substantially reversed with respect to the major direction of droplet travel within the central region. Larger droplets are unable to negotiate the turn from the central to upper regions and impinge on a rear surface of the spray chamber. Removal of larger droplets has the advantageous effect of enabling the detector to sense a smaller range of particle sizes, which establishes a relatively steady electrical current at the detector.

An apparatus for collecting liquid fractions from a separation/reaction apparatus (1). A capillary (2) guides an extracted liquid fraction to a branching unit (3), a collection arrangement (4) carries a plurality of target vessels (5) receiving the liquid fraction from the capillary and a fluid line (6) is flow-connected to a fluid pump (7) and opens into the branching unit. The capillary and the fluid line each have outlet openings in the direct vicinity of one another at their end facing a target vessel such that liquid emerging from the outlet opening (2′) of the capillary transitions into the outlet opening (6′) of the fluid line. This precludes back mixing with earlier/later liquid fractions, precludes uncontrolled dripping of sample substance at the transfer point, speeds displacement of the target vessels in the collection arrangement, facilitates automation of the fraction processing procedure, and results in a more compact fraction collection apparatus.
