Standard Gas Introduction via Carrier Flow Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for introducing a standard gas into a sample vessel for chromatographic analysis are complex and require additional time and hardware modifications, often involving multiple transfer lines and needle assemblies.
Innovation Solution
A method that integrates the introduction of standard gas into the sample vessel using a carrier gas inlet and a receptacle with a vessel port, where the standard gas is introduced into the carrier gas flow path during pressurization, simplifying the process and minimizing hardware modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional methods are used to introduce standard gas into sample vessel, then the standard gas can be introduced, but the process becomes complex and requires additional time and hardware modifications
Solution Approach 1:
The patent combines the standard gas introduction function with the existing carrier gas flow path and receptacle assembly. The standard gas inlet is integrated into the receptacle structure, allowing standard gas to be introduced through the same flow path used for carrier gas, eliminating the need for separate introduction mechanisms and reducing overall system complexity
Solution Approach 2:
The receptacle assembly is designed to serve multiple functions: it acts as both the carrier gas delivery system and the standard gas introduction system. The flow path is configured to handle both carrier gas and standard gas, allowing a single component to perform what would traditionally require separate dedicated systems
2Reliability
If conventional methods are used to introduce standard gas into sample vessel, then the standard gas can be introduced, but additional time is required
Solution Approach 1:
The system is pre-configured with the standard gas inlet positioned within the receptacle, ready for immediate introduction. The flow path is designed to allow standard gas to be injected directly into the carrier gas stream without requiring additional setup or time-consuming manual operations
Solution Approach 2:
The standard gas is introduced continuously into the carrier gas flow path during the normal sampling operation. This allows standard gas introduction to occur simultaneously with carrier gas delivery, eliminating sequential steps and reducing total process time
3Reliability
If additional hardware modifications are made to introduce standard gas, then standard gas introduction is achieved, but the hardware complexity increases
Solution Approach 1:
The standard gas inlet is merged with the receptacle structure, utilizing existing hardware components rather than adding separate introduction devices. The flow path integration allows standard gas to be delivered through the same mechanical infrastructure used for carrier gas
Solution Approach 2:
The carrier gas flow path serves as an intermediary medium to deliver standard gas to the sample vessel. By using the existing carrier gas stream as the delivery vehicle, the system avoids the need for dedicated standard gas delivery hardware

AI summary
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.
