There is growing concern that VOC emissions from materials used indoors in buildings should be monitored to ensure that building occupants are not exposed to potentially harmful chemicals. Monitoring can be absolute (determining, for example, emission rates in micrograms per square meter-hour),
The global golf ball market was estimated to be over one billion dollars in 2017. It is estimated that each year, over 300 million golf balls are lost in the United States, alone. Golf balls are not recyclable or biodegradable, so if not recovered, the balls are left in waterways and woodlands.

Plastics have become a major source of pollution due to their ubiquitous use in a wide array of products. Most plastics are not readily biodegradable and can wind up as litter or are simply disposed of in landfi lls. It is estimated that only 9% of the plastic in the US is recycled [1]. Plastics discarded into the environment can be ingested by animals, break down into smaller particles which can also be ingested, or leach other compounds into the environment which can potentially cause damage. Leachates can include plasticizers, fl ame retardants, blowing agents, UV stabilizers, dyes and a host of other compounds added to the polymers.

Liquid-liquid extractions have long been performed manually and are used to extract and concentrate analytes from aqueous matrices. Inclusion of liquid-liquid extraction in many official methods...
Bisphenol A (BPA) is a widely produced chemical used as a precursor in the formation of plastics (polycarbonate) and coatings for food and beverage containers

Micro- and nanoplastics pollution in oceans, lakes and other water sources is an on-going and well-documented issue. Sources and entry ways of these plastics include grey water, surface runoff, and litter. Grey water is defi ned as the relatively clean wastewater from sources such as baths, sinks, washing machines and dishwashers. The very small plastic particle size precludes effi cient removal during the wastewater treatment process. As a result, fi sh and other aquatic life ingest the plastics, which introduces them into the food chain and causes possible adverse effects.

Stir Bar Sorptive Extraction (SBSE) and Solvent Assisted Stir Bar Sorptive Extraction (SA-SBSE) are firmly established techniques for extraction of compounds from various matrices, with the latter technique offering significant increased capacity for concentration of hydrophilic/polar compounds. In this application note this difference is explored by applying both SBSE and SA-SBSE to a berry-flavored yogurt followed by GC-MS after liquid desorption of the stir bars.
In the work presented here, the perfluorinated carbonic and sulfonic acids listed in the EU Drinking Water Directive (EU 2020/2184) were determined by an automated method based on solid phase extraction with weak anion exchange sorbent combined with LCMS/MS.
This study describes the use of the GERSTEL MultiPurpose Sampler (MPS) fitted with a Thermal Desorption Unit (TDU) and a Cooled Injection System (CIS 4) PTV-type Inlet for the automated direct thermal extraction analysis of packaging for three different brands of crème-filled chocolate...
This application note describes two automated methods for screening of extractable compounds from materials for food packaging, medical or technical purposes. The first method is based on automated liquid extraction performed by the GERSTEL MultiPurpose Sampler (MPS),...
