International Classification:

G01J 5/02

US Classification:

250343

Abstract:

A system for certifying a concentration of gas in a cylinder includes a gas cell configured to receive a sample gas from a cylinder, and an FTIR module coupled to the gas cell for scanning the sample gas and forming a beam spectrum. A processor is coupled to the FTIR module for calculating an intensity response of the sample gas based on the beam spectrum. A storage device is included for storing data points of a plot of intensity response of a known gas versus concentration levels. The processor is configured to interpolate between the stored data points of the plot to determine an interpolated data point corresponding to the intensity response of the sample gas. The processor provides to the user a concentration level of the sample gas, based on the interpolated data point.

Abstract:

A pressurized cylinder containment unit is provided. The pressurized cylinder containment unit comprises a support structure including means for receiving a shelf. The shelf receiving means is/are defined along at least a portion of a height dimension of the support structure. At least one shelf is provided for supporting the one or more pressurized cylinders. The at least one shelf is moveably positionable along the height dimension of the support structure. The at least one shelf includes mounting means for selectively mounting to the shelf receiving means of the support structure at different height elevations.
