Beverage Analysis | Alcoholic Beverages
In the industry for wine, beer, or spirits there is an increasing focus on assessing the quality, purity and authenticity of both raw materials and final product. This increase in focus allows the production process itself to be controlled to ensure more consistent and higher quality products. Several analytic techniques exist to assess each stage of the production process, let assist in selecting the correct workflows for your beverage production.

Beverage Analysis | Non-Alcoholic Beverages
Preservatives such as benzoic acid and sorbic acid are added to extend the shelf life of products, sweeteners are added to replace sugars, while stimulants such as caffeine may be added to increase alertness. Addition of all of these ingredients are subject to regulations, and need to be controlled in food, beverage, and consumer products. Also, in most countries it is a requirement by helalth authorities that the Ca and Na content be labeled on packaged food and beverages. These labeling requirements, as well as the typical quality control analyses carried out by manufacturers, demonstrate the need for simple, cost-effective, sensitive, accurate, precise, and high sample throughput methods for non-alcholic beverage analyses.

Soils, Sudges and Sediments | Inorganics in Soi
Regulatory bodies have a duty to protect the public from exposure to hazardous substances, including potentially toxic heavy metals and other inorganic and organometallic species present in soil. Agilent Spectroscopy instruments are ideal for monitoring these substances—whether naturally occurring or the result of industrial or agricultural activity—because they can provide robust performance and precise quantitative analysis of trace level inorganics.

Water Analysis | Per- and Polyfluoroalkyl Substances (PFAS)
(PFAS) are persistent, bioaccumulative, and a health concern, calls for more regulatory guidance and stringent requirements have increased. As a market leader in environmental analysis for over 40 years, Agilent offers complete start-to-finish workflows for extraction, screening, quantification, and reporting of PFAS in water and environmental samples.

Water Analysis | Pharmaceuticals and Personal Care Products (PPCPs), Hormones & Persistent Organic Pollutants (POPs)
Persistent organic pollutants (POPs) include many different and diverse classes of chemicals including dioxins, furans, polychlorinated biphenyls (PCBs), polybrominated diethyl ethers (PBDEs), polyaromatic hydrocarbons (PAHs), endrin, DDT and others. Research shows that POPs are extremely toxic to humans and wildlife even at very low concentrations. Pharmaceuticals and personal care products (PPCPs) & hormones enter our water supplies through human excretion, domestic and industrial disposal into wastewater treatment plants, agricultural runoff and animal feed lot operations. One of the negatives effects that active hormones found on excrement can have on both humans and wildlife is endocrine disruption, which may occur at extremely low ng/L levels. PPCPs are quite resilient and are difficult to remove through conventional water treatment processes, resulting in persistence in the environment and potential accumulation over time. Agilent offers complete solutions including online and offline solid phase extraction techniques, and LC-MS and GC-MS systems to analyze PPCPs, hormones and POPs at required sensitivity and accuracy levels in the environment.

Water Analysis | Microplastics in Water
Contamination in our waterways, soil, air, and drinking water from microplastics is gaining significant public interest due largely to its emergence as an environmental threat.
Researchers are now working towards standardized analytical solutions to best characterize
these small particles in terms of chemical identity, size, shape, and total mass.

Water Analysis | Metals and Trace Metals Analysis
Ensuring the quality of drinking water is a primary goal for public health around the world. Most countries have enacted regulations and monitoring programs to ensure that the supply of drinking water is free from potentially harmful chemicals. The regulations typically include maximum allowable concentrations for a range of inorganic components. Trace metals are routinely monitored in both the treated water supplied to households, and the source water used for drinking water abstraction (from rivers, reservoirs, lakes, underground aquifers; and, in some regions, seawater used for desalination).
