GCMS/LCMS screening for contamination

GCMS/LCMS screening for identification of contaminants in samples, with the analytical method selected according to sample type.

<p><strong>The GCMS/LCMS Screening for Contamination is a standalone laboratory service designed to identify potential contaminants in a sample using either gas chromatography–mass spectrometry (GCMS) or liquid chromatography–mass spectrometry (LCMS).</strong></p><p>The appropriate analytical method depends on the sample type. GCMS is used primarily for volatile and semi-volatile compounds, while LCMS is suitable for peptide-related contamination.</p><h4><strong>About the Screening</strong></h4><ul><li><strong>GCMS screening</strong> uses the <strong>NIST 2014 </strong>mass spectral library to identify a broad range of potentially <span style="font-weight:400;">harmful substances in the product</span>. Detection is limited to volatile and semi-volatile compounds and this method is not suitable for peptide samples.<br>&nbsp;</li><li><strong>LCMS screening</strong> is intended for peptide products and can detect contamination with other peptides or degraded peptide. Detection is limited to peptides included in the laboratory’s available reference list.</li></ul><p>Both methods provide identification of detected contaminants only. Quantitative determination of a detected substance can be offered separately.</p><h4><strong>Key Features</strong></h4><ul><li>Standalone contamination screening by GCMS or LCMS</li><li>Analytical method selected according to sample type</li><li>GCMS screening for volatile and semi-volatile contaminants</li><li>GCMS identification using the NIST 2014 mass spectral library</li><li>LCMS screening for peptide contamination and degraded peptide</li><li>Identification of detected contaminants</li><li>Quantitative determination available separately after identification</li><li>Suitable for tablets, capsules, liquid solutions, raw materials, and vials depending on the selected method</li><li>Average turnaround time of 7 business days</li></ul><h4><strong>Analysis Parameters</strong></h4><ul><li><strong>Testing method: </strong>GCMS or LCMS</li><li><strong>Amount of sample required: </strong>1 tablet/capsule, 1 ml solution, 200 mg raw material, or 1 vial</li><li><strong>Average turnaround time: </strong>7 business days</li></ul><blockquote><p><strong>Important Notice</strong></p><ul><li>The analytical method is selected according to the type of sample and the expected contaminants.</li><li>GCMS detection is limited to volatile and semi-volatile compounds and cannot be used for peptide samples.</li><li>LCMS detection is limited to peptides included in the laboratory’s available reference list.</li><li>Both GCMS and LCMS screening provide identification only.
