Hair analysis has emerged as a valuable non-invasive technique for assessing long-term exposure to trace elements and heavy metals. At Tamilnadu Test House , we utilize **Inductively Coupled Plasma Mass Spectrometry (ICP-MS)** to perform highly sensitive and precise elemental profiling in hair samples ๐ก **Why Hair?** Unlike blood or urine, hair provides a historical record of elemental exposure over weeks to months, making it an excellent matrix for biomonitoring. ⚙️ **Our Approach:** • Careful sample preparation and washing protocols to eliminate external contamination • Acid digestion to extract embedded elements • High-resolution ICP-MS analysis for multi-element detection at trace levels ๐งช **Elements Typically Analyzed:** Lead (Pb), Mercury (Hg), Arsenic (As), Cadmium (Cd), along with essential minerals like Zinc (Zn), Iron (Fe), Copper (Cu), and more. ๐ **Applications:** ✔️ Environmental and occupational exposure studies ✔️ Toxicological assessments ✔️ Nutritional and metabolic...
