In this microbiology lab short, we perform the catalase test to detect the presence of the catalase enzyme in E. coli. When hydrogen peroxide is added, the formation of bubbles indicates a positive result due to oxygen release. 🫧 Result: Catalase Positive 📚 Purpose: Identify bacteria based on enzyme activity #Microbiology #CatalaseTest #EColi #LabShorts #BiologyLab MedicalLab  

 In today’s highly regulated industrial environment, choosing the right NABL-accredited testing lab in Chennai is critical for ensuring product quality, regulatory compliance, and customer trust. Whether you operate in manufacturing, construction, pharmaceuticals, food processing, or electronics, the accuracy of test results directly impacts safety, performance, and market approval.

Gas Chromatography–Mass Spectrometry (GC-MS) is one of the most powerful analytical techniques used for identifying and quantifying chemical compounds in complex samples. In Chennai, industries such as pharmaceuticals, food processing, environmental monitoring, petrochemicals, cosmetics, and research institutions rely on advanced GC-MS analysis services to ensure product quality, safety, and regulatory compliance. GC-MS combines two highly effective technologies. Gas chromatography separates chemical mixtures into individual components, while mass spectrometry identifies each compound based on its molecular structure and mass-to-charge ratio. This dual capability makes GC-MS analysis highly accurate, sensitive, and reliable, even when dealing with trace-level substances. Why GC-MS Analysis Is Essential GC-MS analysis plays a critical role in detecting unknown compounds, contaminants, impurities, and residues. It is widely used for: Identifying organic and volatile compounds ...
