These solutions help researchers gain clear insights, improve workflow efficiency, and make confident decisions across diverse projects.
Gas Chromatography Testing is a sophisticated analytical approach for separating, identifying, and quantifying volatile and semi-volatile compounds in complex mixtures. The technique exploits differences in how compounds interact with a stationary phase within the chromatography column while being transported by a mobile gas phase, resulting in each component eluting at a specific retention time. Signals from eluted compounds are recorded and transformed into chromatograms, which are then evaluated for retention characteristics, peak intensity, and shape. This analysis supports both qualitative and quantitative determinations, including multi-component separation and detection of trace-level analytes. GC Testing finds broad applications in pharmaceutical development, chemical and materials research, environmental monitoring, food analysis, and other scientific investigations, offering high sensitivity, reproducibility, and reliable data interpretation even for complex sample matrices.
Our Qualitative GC Testing identifies the types and structural characteristics of compounds within a sample. This is particularly valuable for pharmaceutical intermediates, natural products, and complex chemical mixtures, allowing researchers to quickly understand composition and support experimental design and process optimization.
Quantitative GC Testing provides precise measurements of target compound concentrations. Whether analyzing key intermediates in drug development or specific components in food and environmental samples, our results support informed R&D and process decisions.
Combining qualitative and quantitative approaches, GC Testing delivers both compound identification and concentration data in a single report. This reduces repetitive experiments and accelerates the development process by providing comprehensive sample information.
For multi-component samples, our Complex Mixture GC Testing separates and resolves overlapping peaks to produce clear, interpretable chromatograms. This enables researchers to gain actionable insights into complex mixtures, improving accuracy and reliability of experimental conclusions.
Trace Component GC Testing provides high-sensitivity analysis for low-concentration or trace compounds. Whether detecting trace impurities in pharmaceutical samples or volatile compounds in environmental and food matrices, our services ensure that even minor components are reliably quantified.

At BOC Sciences, our GC Testing services support a broad range of sample types, showcasing the versatility of gas chromatography and our analytical expertise. We handle pharmaceutical intermediates and precursors, including small-molecule organic compounds and active intermediates, as well as synthetic chemicals such as organic synthesis products and laboratory-prepared mixtures. Our services extend to natural products and plant extracts, complex botanical extracts, and essential oils, alongside food and nutritional components, environmental samples including air, water, soil, and sediment, and materials and polymers containing volatile components.
To ensure accurate and reliable GC Testing results, we provide guidance on sample preparation and handling. We analyze samples in different physical states, including gases, liquids, or solids, with solids possibly requiring dissolution or derivatization. GC-compatible solvents like acetonitrile, methanol, or dichloromethane are recommended. Typical sample volume or weight ranges from micrograms to milligrams. Samples should fall within the instrument detection range, and we provide dilution guidance for low-concentration or trace samples. Volatile or labile samples may require cold-chain transport or protective packaging.
To ensure smooth processing and accurate results, clients should provide clear sample identification, including sample ID, composition, and intended analysis targets. For hazardous or high-risk materials, a Safety Data Sheet (SDS) is required. Sharing purity and matrix details helps select optimal columns and detectors. Additionally, polar, non-volatile, or complex matrix samples may need special handling, such as derivatization, solid-phase microextraction (SPME), or other pre-treatment methods. These steps help us deliver high-quality, reliable GC Testing results tailored to each client's research needs.
Provide your sample name, type, quantity, and analysis requirements. Include any special handling instructions or preferred report format. Our team will review your submission promptly and provide a personalized quote.
