Introduction
human health from additional PFAS accumulation and exposure.
And with ever-decreasing allowable limits, the need for more
analytical standards is increasingly important.

Per- and polyfluoralkyl substances (PFAS) are a class of industrial
chemicals that are used to resist grease, oil, water, and heat.
They are most commonly used in the manufacture of waterand stain-resistant fabrics and carpeting, food packaging, andfire-fighting foams.
PFAS have been one of the most discussed classes of chemical
pollutants in recent years due to their widespread use, prevalenceand persistence in the environment, and human-exposure concerns.
Regulatory agencies worldwide have begun proposing or enactingbans on certain PFAS compounds to protect the environment andCIL has been working diligently to produce high-purity stable
isotope-labeled and native individual and multi-component PFAS
standards to assist with ongoing environmental and biomonitoringstudies. More standards are being developed and released as newcompounds of concern are identified and standardized methods
are established.

You can find all of the information presented in this catalog on isotope.com. Visitors to our website can immediately accessupdated product information, availability, pricing, and documentation, such as a certificates of analysis (CoA) and safety data
sheets (SDS). Visit isotope.com to learn more.
Chemical purity for unlabeled/native compounds is 97-99% or greater unless otherwise specified; chemical purity for labeled
compounds is 95-99% or greater unless otherwise specified.

Standards for Environmental Analysis
Through our collaborations with environmental testing laboratories, regulatory agencies, andresearch institutions around the world, CIL has developed numerous products to assist a wide
range of testing applications. You will find more than 3,000 products developed specifically fortrace and ultratrace analysis by isotope dilution mass spectrometry (IDMS). As new technology andmethodologies advance, CIL maintains a leadership role in developing new standards and standard
mixtures to keep pace with these new procedures. You will find throughout this catalog many new
products developed in various solvents for use in not only new GC-MS applications, but also
LC-MS methods that continue to gain importance as an integral part of the environmental
testing laboratory.
