BOC Sciences provides a comprehensive range of pharmaceutical analysis methods, including gravimetric methods, acid-base titration methods, pH value determination methods, spectroscopic techniques, chemiluminescence techniques, chromatography, electrophoresis, DNA amplification methods, etc. These analytical techniques are critical for the characterization and quality control of pharmaceutical products, ensuring drug safety and effectiveness. With state-of-the-art instrumentation and a team of experienced scientists, BOC Sciences is committed to providing accurate and reliable drug analysis services to support the pharmaceutical industry and advance the development of new therapeutics.

Gravimetric Analysis

Gravimetry is a basic technique in pharmaceutical analysis that involves measuring the mass of a substance to determine its purity or concentration. This method is based on the principle that the mass of a pure substance is directly proportional to its chemical composition. Gravimetric analysis is commonly used to determine the purity of drug substances and the content of active pharmaceutical ingredients (APIs) in pharmaceutical products. BOC Sciences utilizes state-of-the-art analytical balances and precision weighing technology to ensure accurate and reliable results.

Acid-Base Titration Analysis

Acid-base titration is another important tool in pharmaceutical analysis, especially for determining the concentration of acids and bases in pharmaceutical preparations. The method involves the gradual addition of a known concentration of titrant to the analyte until the equivalence point is reached, at which point the reaction is stoichiometrically complete. BOC Sciences can perform acid-base titrations with high precision and accuracy using automated titration systems and high-quality reagents.

pH Value Determination

pH measurements are critical for assessing the acidity or alkalinity of pharmaceutical formulations and monitoring the stability of drug substances. BOC Sciences utilizes pH meters and electrodes to measure the pH of drug solutions and formulations, ensuring the pH is within the specified range for optimal stability and efficacy.

Spectroscopic Techniques

Spectroscopic techniques, including UV-visible spectroscopy, infrared (IR) spectroscopy, and nuclear magnetic resonance (NMR) spectroscopy, are powerful tools in pharmaceutical analysis for identifying and quantifying drugs. BOC Sciences has extensive experience in applying spectroscopic techniques for pharmaceutical analysis, using advanced spectrophotometers and spectrometers to obtain accurate and reliable results. Our UV-Vis spectroscopy is often used for quantitative analysis of drugs because it is sensitive to the presence of chromophores in drug molecules. Infrared spectroscopy can be used to identify functional groups in drugs, while NMR spectroscopy can provide detailed structural information about drug molecules.

Chemiluminescence Techniques

Chemiluminescence technology is used in pharmaceutical analysis to detect specific compounds based on their ability to emit light as a result of chemical reactions. This method is particularly useful for the determination of trace impurities or contaminants in pharmaceutical products. BOC Sciences also supports the use of chemiluminescence analyzers to detect and quantify low-level impurities in drug substances and dosage forms to ensure drug safety and quality.

Chromatographic Analysis

Chromatography is a versatile and widely used technique in pharmaceutical analysis and includes methods such as high-performance liquid chromatography (HPLC), gas chromatography (GC), and thin-layer chromatography (TLC). HPLC is the most commonly used chromatographic method in pharmaceutical analysis, providing high resolution and sensitivity for the separation and quantification of drug substances and impurities. GC is suitable for the analysis of volatile compounds, while TLC is a simple and cost-effective method for qualitative analysis of pharmaceuticals. BOC Sciences has extensive expertise in the application of chromatography techniques for pharmaceutical analysis, and we typically utilize state-of-the-art chromatography systems and columns to achieve accurate and precise separations of various forms of pharmaceuticals.

Electrophoretic Analysis

Electrophoresis is a powerful technique used to separate and analyze charged molecules such as proteins, nucleic acids, and carbohydrates. This method is widely used in the characterization of biopharmaceuticals and the analysis of drug impurities. BOC Sciences can analyze pharmaceutical products using capillary electrophoresis and gel electrophoresis, providing detailed information on the composition and purity of the drug substance.

DNA Amplification Techniques

DNA amplification methods, such as polymerase chain reaction (PCR), are critical for the detection and quantification of nucleic acid sequences in pharmaceutical products. This method is particularly important for the analysis of biopharmaceuticals, including gene therapies and recombinant proteins. BOC Sciences is committed to ensuring the safety and quality of biopharmaceutical products by utilizing PCR and other DNA amplification technologies to detect and quantify nucleic acid impurities with high sensitivity and specificity.
