Dependable information from the Chemical Enquiries Help Desk in 48 hours.  Each month library staff look at one of the many enquiries received and highlight selected resources, including the Virtual Library, that provide relevant answers.  

The enquiry this month 

• What recent literature is there on the detection of PCBs (polychlorinated biphenyls) in milk.              

The full text of quality analytical chemistry journals has recently been made available to members in ScienceDirect through the RSC Virtual Library.  Titles include:

• Analytica Chimica Acta
• Analytical Biochemistry
• Journal of Chromatography A 
• Journal of Chromatography B 

Examples of just some of the journals articles on the topic include: 

Two-dimensional gas chromatography coupled to triple quadrupole mass spectrometry for the unambiguous determination of atropisomeric polychlorinated biphenyls in environmental samples
Journal of Chromatography A, Volume 1110, Issues 1-2, 31 March 2006, Pages 156-164

Neuro-genetic multioptimization of the determination of polychlorinated biphenyl congeners in human milk by headspace solid phase microextraction coupled to gas chromatography with electron capture detection
Analytica Chimica Acta, Volume 585, Issue 1, 28 February 2007, Pages 66-75

Polychlorinated biphenyls (PCBs) detection in milk samples by an electrochemical magneto-immunosensor (EMI) coupled to solid-phase extraction (SPE) and disposable low-density arrays
Analytica Chimica Acta, Volume 594, Issue 1, 26 June 2007, Pages 9-16
