Compound & Forensic Testing

Compound & Forensic Testing: Advanced Analytical Techniques for Precision Identification

Compound and forensic testing involves the precise analysis and identification of chemical substances using advanced instrumentation and methodologies. Utilised in pharmaceuticals, law enforcement, and research laboratories, these techniques ensure accurate characterisation of complex compounds.

Key analytical methods include:

  • FTIR (Fourier Transform Infrared Spectroscopy) – Identifies molecular structures based on infrared absorption spectra.
  • NMR (Nuclear Magnetic Resonance Spectroscopy) – Provides detailed structural insights into organic and inorganic compounds.
  • GC-MS (Gas Chromatography-Mass Spectrometry) – Detects and quantifies volatile and semi-volatile compounds with high sensitivity.
  • LC-MS (Liquid Chromatography-Mass Spectrometry) – Separates and identifies chemical components in complex mixtures.
  • HPLC (High-Performance Liquid Chromatography) – Ensures precise quantification and purity assessment of chemical substances.

These cutting-edge analytical techniques are crucial in forensic toxicology, drug analysis, environmental testing, and quality control, ensuring scientific accuracy and compliance with regulatory standards.

How to Safely Send Chemical Samples for Analytical Testing

To ensure accurate, efficient analysis and compliance with safety regulations, please follow these detailed instructions when preparing and shipping your chemical samples for FTIR, NMR, GC-MS, LC-MS, or HPLC analysis:

1. Sample Labelling and Documentation

  • Clearly label all samples with your company name, contact information, sample identification number, date, chemical name or identifier (if known), and analysis required.
  • Include a detailed sample submission form specifying the analytical method requested (FTIR, NMR, GC-MS, LC-MS, or HPLC), and clearly state any known hazards associated with the sample.

2. Appropriate Sample Containers

  • Use chemically compatible containers such as:
    • Solid samples: tightly sealed, chemically resistant screw-cap vials or containers made of glass or chemically inert plastic (e.g., polyethylene, polypropylene).
    • Liquid samples: leak-proof, chemically resistant glass vials or bottles with secure screw-top caps. Ensure seals are intact and secure.
    • Gas samples: appropriate gas-tight containers or pressurised cylinders, clearly labelled, and compliant with transport regulations.

3. Secure and Protective Packaging

  • Primary containment: Ensure the sample container is tightly sealed. For liquids, seal container caps with parafilm or PTFE tape to prevent leakage.
  • Secondary containment: Place each sealed sample into a chemically resistant secondary container, such as a zip-lock or heat-sealed bag, to provide added leak protection.
  • Cushioning and padding: Use appropriate padding materials such as bubble wrap, foam padding, or absorbent materials to prevent breakage or movement during transit.
  • Outer packaging: Select a sturdy, rigid outer shipping box or container to withstand transport handling.

4. Safety Compliance and Hazard Declaration

  • Clearly declare any hazardous or regulated substances, adhering strictly to UK/EU shipping regulations.
  • Include appropriate hazard labels and comply with relevant transport regulations, including:
    • UN classification (if applicable)
    • Proper shipping names and hazard classes
    • Material Safety Data Sheets (MSDS) where applicable

5. Shipping and Delivery

  • Choose a reliable, licensed courier service experienced in transporting chemical and laboratory materials (e.g., DHL, FedEx, TNT, or specialist couriers).
  • Provide tracking information and inform us in advance of your shipment, if possible, to facilitate prompt handling upon receipt.

6. Receiving Confirmation and Analysis

  • Upon receipt, we will confirm the safe arrival and the integrity of your samples.
  • The analysis will commence according to your specified method (FTIR, NMR, GC-MS, LC-MS, or HPLC), followed by the timely delivery of comprehensive analytical reports.

By strictly adhering to these guidelines, you help ensure sample integrity, regulatory compliance, safe handling, and prompt, accurate analytical results.
