Analytical Chemistry

Mass spectrometry (MS) is an important tool when specific compounds and materials must be identified with a high degree of precision. It is widely utilized in food quality and safety, drug testing, analyzing pesticide residue, and protein identification.

High-performance liquid chromatography (HPLC) and ultra-high-performance liquid chromatography (UHPLC) are among the most widely used analytical techniques in the chemical and life sciences.

Preparative or purification chromatography is used to isolate compounds in quantities and at purity levels needed for further experiments or processes by separating them from starting materials, side reactions or other impurities.

Gas chromatography (GC) employs insert gases to separate, identify, and quantify volatile sample mixtures in food, environmental, and chemical industries. Avantor carries a variety of columns, solvents, consumables and gas generators

Atomic spectroscopy encompasses a group of analytical techniques based on how atoms absorb and emit electromagnetic radiation, including atomic absorption spectroscopy (AA) and inductively coupled plasma (ICP).

Molecular spectroscopy represents a collection of analytical techniques based on how molecules absorb light, including ultraviolet/visible (UV/Vis), infra-red (IR), Fluorescence, and NMR that are routinely used in key applications within pharmaceuticals

Titration refers to quantitative chemical analysis based on a reaction between a component of a sample and another substance with which that component of interest reacts in a definite, known proportion.

Karl Fischer titration (KF) is the leading method for measuring water content in a wide variety of products and industries, such as chemicals, petroleum products, foods, pharmaceuticals, and many others.

These electrochemical techniques provide powerful and versatile analytical options that feature high sensitivity, accuracy, and precision, utilizing relatively lower cost instrumentation than other methods of analysis.

Compounds may act differently based on their physical structure. Avantor has the instruments and equipment you need to identify compounds by looking at their refractive index, melting point, or other physical characteristic.

X-ray fluorescence spectroscopy, or XRF, lets analysts obtain qualitative and quantitative information by measuring the fluorescent X-rays that are emitted from a sample when X-rays are projected onto the sample from an outside source.
