Abstract
A method for discovering amounts of halogen in a liquid is provided wherein the a reservoir comprising the liquid and suspected halogen is healed to a temperature characteristic of the solubility of halogen in the liquid to provide a vapor. After condensing, a sampling vapor is provided to from which the amount of halogen may be detected.

Apparatus for taking samples of a liquid from a plurality of corresponding spaces and monitoring the samples of liquid to detect a leak into the liquid of a given gas of a given concentration level which is greater than a residual level of the given gas, said apparatus comprising:
- a) a plurality of actuable valves, each of said valves in communication with a respective one of said plurality of spaces;
- b) a common sampling reservoir in communication with each of said plurality of valves for receiving the sample of the liquid from an actuated one of said plurality of valves;
- c) means for separating the given gas present in the liquid of the sample in said sampling reservoir;
- d) gas detecting means in communication with said sampling reservoir for detecting the presence of the separated gas of a concentration above the given concentration level to provide an alarm indicative of a valid leak of the given gas into a corresponding liquid sample;
- and
- e) controlling means including means coupled with each of said plurality of actuable valves for selectively actuating one of said plurality of valves to permit the introduction of one sample of the liquid at a time from the corresponding one of said plurality of spaces into said sampling reservoir and the subsequent detection by said gas detecting means of the separated given gas in the one sample.
A method for taking samples of a liquid from a plurality of corresponding spaces and monitoring the samples for the suspected presence of a given gas leaked into the liquid in any of said plurality of spaces of a given concentration level greater than a residual level of the given gas, said method comprising the steps of:
- a) taking one sample of the liquid at a time from a selected one of the plurality of spaces and introducing the one liquid sample into a common sampling reservoir;
- b) separating the given gas present in the liquid of the one sample introduced into the sampling reservoir;
- c) conveying the given gas separated into the sampling reservoir to a sensor;
- and
- d) operating the sensor to detect the presence of the given gas separated from the one sample of a concentration above the concentration level to produce an alarm indicative of a valid leak of the given gas into a corresponding liquid sample.
Apparatus for taking samples of a liquid from a plurality of corresponding spaces and monitoring the samples of liquid to detect a leak into the liquid of a given gas of a given concentration level which is greater than a residual level of the given gas, said apparatus comprising:
- a) a single conduit having a plurality of ports therein;
- b) a corresponding plurality of actuable valves, each of said valves in communication with a respective one of said plurality of spaces and a respective one of said plurality of ports;
- c) a common sampling reservoir coupled to said single conduit for receiving the sample of the liquid from an actuated one of said plurality of valves;
- c) means for separating the given gas present in the liquid of the sample in said sampling reservoir;
- d) gas detecting means in communication with said sampling reservoir for detecting the presence of the separated gas of a concentration above the given concentration level to provide an alarm indicative of a valid leak of the given gas into a corresponding liquid sample;
- and
- e) controlling means including means coupled with each of said plurality of actuable valves for selectively actuating one of said plurality of valves to permit the introduction of one sample of the liquid at a time from said corresponding one of said plurality of spaces into said sampling reservoir and the subsequent detection by said gas detecting means of the separated gas in the one sample.
