Patent number: 10677767Abstract: In one embodiment, an improved gas analysis system having a gas flow cell is provided. In another embodiment an improved gas flow cell is provided. As disclosed herein, dead volumes in a gas flow channel of a gas flow cell may be minimized through the use of one or more additional gas inlets. In one embodiment, an additional gas inlet is located between an analyte gas inlet and a light entrance optical coupling of the gas flow cell. In another embodiment, an additional gas inlet is located between an analyte gas outlet and a light exit optical coupling of the gas flow cell. In addition, enclosed regions may be formed adjacent seals of the gas flow channel of the gas flow cell. The enclosed regions may be evacuated and/or purged so as to minimize the passage of contaminants through the seals into the gas flow channel.Type: GrantFiled: June 12, 2018Date of Patent: June 9, 2020Assignee: VUV Analytics, Inc.Inventors: Dale A.
