Rapid and reliable phthalate screening in plastics by portable FTIR spectroscopy

نویسنده

چکیده

A quantitative method for determining the level of plasticizer in plastics is now available for Agilent portable and handheld FTIR analyzers. The calibrated method affords a limit of quantitation as low as 0.1% as well as provides a very rapid means of screening plastic products and components. This ensures that greater volume of plastic materials can be screened more effi ciently for compliance with regulatory guidelines.

Measuring and Verifying Performance of FTIR for Rapid Phthalate Screening

Phthalates are widely used as plasticizers to make polymers more flexible in industrial and household products. However, lower molecular weight ortho-phthalate plasticizers have serious health effects and are restricted or banned in many countries for use in children’s products. In addition, several government agencies restrict or are investigating restricting ortho-phthalates (ortho-dialkyl ph...

Analysis of Adipate Ester Contents in Poly(vinyl Chloride) Plastics by Means of Ft-raman Spectroscopy

Fourier transform (FT-) Raman spectroscopy excited with a 1064 nm laser can be used to determine the content of plasticizers in commercial flexible poly vinyl chloride (PVC) products. Our previous study [T. Nørbygaard, R.W. Berg, Analysis of phthalate ester content in PVC plastics by means of FT-Raman Spectroscopy, Appl. Spectrosc. 58 (4) (2004) 410–413]—on detection of the presence of phthalat...

Rapid classification and quantification of cocaine in seized powders with ATR-FTIR and chemometrics.

Traditionally, fast screening for the presence of cocaine in unknown powders is performed by means of colour tests. The major drawbacks of these tests are subjective colour evaluation depending on the operator ('50 shades of blue') and a lack of selectivity. An alternative fast screening technique is Fourier Transform InfraRed (FTIR) spectrometry. This technique provides spectra that are diffic...

A concern on phthalate pollution of herbal extracts/medicines and detection methods

Esters of phthalates, mainly applied as plasticizer, cause several human health and environment    hazards. Phthalates are widely used in pharmaceutical products, cosmetics, as well as other plastic commercial products, and can penetrate in foods, water dusts, and air leading to ingestion and inhalation exposure followed by skin absorption for human. These compounds cause serious adverse effect...

Microtiter plate cultivation of oleaginous fungi and monitoring of lipogenesis by high-throughput FTIR spectroscopy

BACKGROUND Oleaginous fungi can accumulate lipids by utilizing a wide range of waste substrates. They are an important source for the industrial production of omega-6 polyunsaturated fatty acids (gamma-linolenic and arachidonic acid) and have been suggested as an alternative route for biodiesel production. Initial research steps for various applications include the screening of fungi in order t...
