The system can include a valve system, a dewpoint control zone, and a multi-capillary column trapping system (MCCTS). During a first time period, the valve system can couple the dewpoint control zone to the MCCTS. During a second time period, the valve system can couple the MCCTS to the chemical separation column such the dewpoint control zone is bypassed. Excess water included in the sample can condense in the dewpoint control zone as the sample transfers to the dewpoint control zone and MCCTS. When the sample is transferred from the MCCTS to the chemical separation column, the condensed water in the dewpoint control zone is not transferred to a chemical separation column."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sample preconcentration system and method for use with gas chromatography","description":"The disclosed system and method concentrates and enriches a chemical sample while removing water and/or CO2 prior to analysis, improving detection limits and repeatability of quantitative chemical ana","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11247204","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
