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.

Technical Overview

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).

Water Analysis | Pesticides

Pesticides & Herbicides compounds used to control weeds, mold, bacteria, insects, and rodents are widely used throughout the world. Due to their widespread use, agricultural chemicals find their way into the food chain, water supply, and soil resulting in potentially dangerous exposure levels to humans. While not fully understood, exposure to pesticides may interfere with neurological development and disrupt a person’s endocrine system. For a complete characterization and sensitive quantification of pesticides in the environment, both an LC-MS and GC-MS system are required. Agilent’s complete workflow solutions for pesticides analysis include sample preparation products, chromatography, mass spectrometry, data reporting and expert application services, provide everything needed to tackle challenges associated with pesticide analysis in the environment.

Water Analysis | Disinfection Byproducts

Disinfection byproducts (DBPs) are formed when organic matter in water reacts with disinfectants used to kill microbes at water treatment plants. DBPs consist of a large variety of mainly halogenated compounds that have been shown to have adverse health effects on humans. Reseach shows that that they may be carcinogenic and may cause both developmental and reproductive issues in humans and wildlife. Common DBP classes are trihalomethanes (THMs), haloacetic acids (HAAs) and Nitrosamines, a class of DBPs that have been shown to be carcinogenic at extremely low ng/L levels. Agilent triple quadrupole LC- & GC-MS systems are the ideal instruments for low-level detection (sub-parts per trillion) of emerging & unregulated DBPS in drinking water.

To identify new disinfection byproducts, the Agilent Q/TOF instruments are ideal partners, offering high-resolution accurate mass analysis with simple yet powerful software tools.
