For companies working in pharmaceuticals, biotech, nutrition, and other regulated sectors, reliable chemical analysis is critical. Two essential techniques that underpin high-precision testing are liquid chromatography and Amino Acid Testing. At Butterworth Laboratories Limited, these techniques are carried out with exceptional accuracy, helping clients meet strict quality standards and regulatory compliance.
In this article, we explore how Butterworth Laboratories delivers excellence in both liquid chromatography and amino acid testing, supporting clients across a range of industries.
What is Liquid Chromatography?
Liquid chromatography (LC) is a powerful analytical technique used to separate, identify, and quantify components in a mixture. It works by passing a liquid sample through a column packed with a stationary phase. Different substances in the sample travel through the column at varying speeds, allowing them to be separated and analysed.
Butterworth Laboratories specialises in high-performance liquid chromatography (HPLC), which offers superior sensitivity and resolution. This technique is widely used in pharmaceutical quality control, raw material testing, stability studies, and product release testing.
Applications of Liquid Chromatography in Industry
Liquid chromatography is vital for:
- Pharmaceutical analysis: Identifying impurities, active ingredients, and degradation products.
- Nutritional testing: Verifying vitamin and nutrient content in food and supplements.
- Environmental monitoring: Detecting contaminants in soil or water samples.
- Cosmetic testing: Ensuring product formulations comply with health and safety standards.
Butterworth Laboratories applies LC methods in compliance with major pharmacopeias and regulatory guidelines, including ICH, BP, EP, and USP standards. Their skilled analysts develop and validate custom LC methods tailored to each client’s product.
Why Choose Butterworth for Liquid Chromatography?
Butterworth Laboratories brings over four decades of experience in chromatographic analysis. Their LC facilities are equipped with state-of-the-art instrumentation, including UV-Vis, diode array, and mass spectrometry detectors.
Clients benefit from:

Whether you’re performing routine batch release or complex impurity profiling, Butterworth provides dependable liquid chromatography services with unmatched precision.
The Importance of Amino Acid Testing
Amino acids are the building blocks of proteins, making their analysis essential in many scientific and commercial fields. Amino Acid Testing determines the type and concentration of amino acids in a given sample. This testing is especially valuable in:
- Pharmaceutical manufacturing: For testing protein-based drugs and excipients
- Nutritional science: To assess protein content in supplements or food products
- Biotechnology: For studying recombinant proteins and enzymes
- Veterinary and agricultural sectors: For analysing feedstock and plant materials
Butterworth Laboratories offers a dedicated Amino Acid Testing service that combines technical accuracy with regulatory rigour.
Advanced Amino Acid Testing at Butterworth
Butterworth employs both pre-column and post-column derivatisation techniques, using HPLC for amino acid analysis. Their lab handles both hydrolysed and free amino acid samples, giving clients comprehensive insight into protein content.
Highlights of their testing capabilities include:
- Analysis of 18 to 22 amino acids in a single run
- Use of acid, alkaline, and enzymatic hydrolysis techniques
- High-sensitivity detection using UV and fluorescence
- Data delivered in line with GMP and GLP standards
Clients can count on Butterworth’s amino acid assays for both R&D and QC environments. From method development to routine analysis, the team ensures data integrity at every step.
