    Mass spectrometry uses high-energy particle beam to transform molecules into gaseous ions, and the decomposed cations are accelerated into the mass analysis instrument. The mass spectra can be obtained by recording and collecting them in the order of m/z ratio. It is one of the most powerful tools for the identification of pure substances, including determination of relative molecular weight, determination of chemical formula and structure identification. Combined with chromatograph and computer, qualitative separation and quantitative analysis can be realized. As a professional reliability third-party testing organization, T,C&A Lab's Mass Spectrometry Testing Laboratory can perform a full range of analysis services according to ISO, ASTM and other standards as well as industry requirements. Welcome to contact our experts for consultation.

    Analysis and testing capabilities of mass spectrometry

    • Relative molecular weight measurement

    • Chemical formula determination

    • Structure identification

    • Quantitative analysis

    Sample requirements

    • The sample for GC-MS analysis should be an organic solution, and the organic matter in the aqueous solution can not be determined generally, so it must be extracted and separated into an organic solution, or the headspace injection technique should be used.

    • Some compounds are too polar and easy to decompose in the heating process, such as organic acids. At this time, the acid can be esterified and then analyzed by GC-MS. The structure of the acid can be inferred from the analysis results.

    • If the sample cannot be vaporized or esterified, it can only be analyzed by LC-MS.

    • The best sample for LC-MS analysis is aqueous solution or methanol solution, and the LC mobile phase should not contain non-volatile salts.

    • For polar samples, ESI source is generally used, and for non-polar samples, APCI source is used.
