Bromine analysis: oxygen flask combustion
Exeter Analytical provides precise bromine analysis using Oxygen Flask Combustion for organic compounds, polymers, pharmaceuticals, cosmetics, and complex matrices. Samples are combusted in an oxygen-rich flask, enabling accurate quantification. Our UKAS ISO/IEC 17025:2017 accredited method (SOP 54) ensures reliable results across high and low bromine concentrations while managing interfering elements. This method delivers consistent, reproducible measurements for research, quality control, and regulatory compliance, making it suitable for both challenging industrial samples and routine testing.
Our chlorine testing uses Oxygen Flask Combustion and a refined Cheng's method to convert chlorine into measurable chloride ions. Optimised for organic and inorganic compounds, this UKAS-accredited method (SOP 57) ensures high accuracy, even in samples containing metals, fluorine, phosphorus, bromine, or iodine. It can be combined with CHN analysis, mass spectrometry, and NMR for comprehensive compound characterisation. Trusted for precision and reliability, Exeter Analytical provides robust chlorine determination for regulatory, R&D, and quality control applications.
Chlorine Analysis: Oxygen Flask Combustion
CHN Analysis: Carbon, Hydrogen, Nitrogen
Exeter Analytical delivers reliable CHN elemental analysis using the CE440 Elemental Analyser. Our method suits diverse samples, including pharmaceuticals, cosmetics, environmental materials, petrochemicals, and research compounds. The horizontal sample introduction system minimises contamination, ensuring accurate and reproducible results. We provide bulk or single-sample testing, determine organic compound purity, and detect inorganic contamination. With UKAS ISO/IEC 17025:2017 accreditation, expert guidance, and rapid reporting, our CHN services support quality assurance, research development, and compliance requirements across multiple industries.
Fluorine analysis
Accurate fluorine determination is essential for food safety, environmental testing, pharmaceuticals, and polymers. Our method combusts samples in a silica flask over a TISAB solution, optimising conditions for fluoride ion measurement. Using a fluoride ion-selective electrode, we achieve precise calibration and reliable quantification. Accredited by UKAS ISO/IEC 17025:2017, our fluorine testing ensures high accuracy, regulatory compliance, and quality control, supporting R&D and industrial applications requiring meticulous control of fluorine content.
Heavy metals testing
Exeter Analytical offers heavy metals testing using established and colourimetric limit tests. Our method visually compares sample intensity against standards to ensure metal impurities remain below limits. Ideal for pharmaceuticals, dietary supplements, and chemicals, it ensures product safety and regulatory compliance. Cost-effective and reliable, this testing supports legacy products and quality control, with expert interpretation provided by experienced analysts, delivering peace of mind for manufacturers needing validated heavy metal analysis.
Our ICP-OES services provide rapid and accurate multi-element analysis for metals in complex samples. With single, multiple, and quantitative full scans up to 69 elements, our UKAS-accredited laboratory handles challenging matrices, including nitric and hydrofluoric acid digestion. ICP-OES analysis supports heavy metals testing, regulatory compliance, and material characterisation. Flexible scanning levels allow qualitative or quantitative results for trace or high concentration elements, making it ideal for R&D, industrial quality control, and environmental monitoring.
ICP-oes metals analysis
Iodine analysis: Leipert’s method
Exeter Analytical offers iodine testing using the reliable Leipert's method. This chemical procedure converts iodine into a measurable form for precise quantification. UKAS ISO/IEC 17025:2017 accreditation ensures rigorous standards, producing accurate results across a range of materials. Ideal for research, quality control, and regulatory compliance, our iodine analysis supports pharmaceutical, environmental, and industrial applications. Clients benefit from expert guidance and dependable reporting, guaranteeing consistent, reproducible, and high-quality analytical data for every sample tested.
Optical rotation analysis
Our Optical Rotation services measure molecular chirality and enantiomeric purity with ±0.0020 accuracy. Multi-wavelength measurements (365–589nm) and precise temperature control at 25°C ensure reliable results. Applications include new compound characterisation, pharmaceutical quality control, and determining enantiomeric purity. Providing high-quality data, Exeter Analytical supports R&D, chemical development, and regulatory compliance. Sample submission is simple, typically requiring 2–30mg, with specific concentration, solvent, and temperature details for accurate and reproducible optical rotation analysis.
NMR spectroscopy
Nuclear Magnetic Resonance (NMR) spectroscopy at Exeter Analytical enables detailed structural elucidation of organic molecules. Using a 400 MHz instrument, we analyse multiple nuclei (1H, 13C) for compound identification, reaction monitoring, mixture analysis, and conformational studies. Applications include organic synthesis verification, R&D, and quality control. Sample requirements vary (5–50mg), with COSHH data for safe handling. Our experienced team provides expert interpretation and reliable reporting, supporting research, regulatory compliance, and comprehensive molecular characterisation across diverse scientific fields.
Exeter Analytical’s FT-IR spectroscopy uses Attenuated Total Reflectance (ATR) for accurate compound identification and impurity detection. Our service supports quality control, functional group analysis, and compound verification with minimal sample preparation. Suitable for liquids, solids, and diverse matrices, it provides fast, reliable, and reproducible results. Sample submission typically requires 5mg with COSHH information. IR spectroscopy is ideal for R&D, manufacturing QA, and regulatory compliance, offering robust data for molecular identification and consistency assurance across industries.
Infra-Red (IR) spectroscopy
Thermal analysis services
Our thermal analysis techniques investigate changes in physical and chemical properties under controlled heating or cooling. Services include Differential Scanning Calorimetry (DSC) for phase transitions, Thermo Gravimetric Analysis (TGA) for decomposition and moisture content, and Sulphated Ash determination for inorganic residues. These methods provide insights into stability, composition, and material behaviour. Accredited and performed by experienced analysts, Exeter Analytical supports material R&D, quality control, and regulatory compliance across pharmaceuticals, chemicals, and industrial applications.
Sulphated Ash testing
Sulphated Ash testing measures inorganic impurities or non-volatile residues in samples. The method combusts the sample with sulfuric acid, stabilising residues for accurate weighing. Applicable to pharmaceuticals, chemicals, and food products, it ensures purity, regulatory compliance, and quality assurance. Exeter Analytical delivers reliable and reproducible results with controlled procedures, enabling confident decision-making for material assessment. This testing is crucial for verifying excipients, APIs, and chemical additives, maintaining consistent product standards and safety.
