Country codes in brackets are obsolete ICIREPAT codes. Country codes in parentheses were used by Derwent PubHcations Ltd. prior to the adoption of International Standards Organization (ISO) country codes. The obsolete codes remain on printed records, but have been replaced by current codes in on-line DATABASES. Eor Japanese patents, Derwent replaced the second character of the country code with the first digit of the pubHcation year prior to 1992 this variant of the company code is stiU found in on-line databases and printed pubHcations. 

Figure 38, Patterns obtained from the extract of 10 fd of serum for lipid fraction by thin-layer chromatography. In sequence, starting from the bottom, phospholipids, pee cholesterol, cholesterol aniline as an internal standard, triglycerides, and cholesterol esters. The free fatty acids occur between cholesterol and the internal standard and are only barely visible in the print, on the extreme right. They are readily visible, normally, to the eye.

HS-GC methods have equally been used for chromatographic analysis of residual volatile substances in PS [219]. In particular, various methods have been described for the determination of styrene monomer in PS by solution headspace analysis [204,220]. Residual styrene monomer in PS granules can be determined in about 100 min in DMF solution using n-butylbenzene as an internal standard for this monomer solid headspace sampling is considerably less suitable as over 20 h are required to reach equilibrium [204]. Shanks [221] has determined residual styrene and butadiene in polymers with an analytical sensitivity of 0.05 to 5 ppm by SHS analysis of polymer solutions. The method development for determination of residual styrene monomer in PS samples and of residual solvent (toluene) in a printed laminated plastic film by HS-GC was illustrated [207], Less volatile monomers such as styrene (b.p. 145 °C) and 2-ethylhexyl acrylate (b.p. 214 °C) may not be determined using headspace techniques with the same sensitivities realised for more volatile monomers. Steichen [216] has reported a 600-fold increase in headspace sensitivity for the analysis of residual 2-ethylhexyl acrylate by adding water to the solution in dimethylacetamide. 

Designing an array is not a trivial task. In addition to the probes of interest, an array should include appropriate numbers of positive and negative control elements, such as housekeeping genes and controls that can be used to monitor the efficiency of important steps within the process. For example, you may wish to spike in internal standards that track recovery or labeling efficiency among different samples. It is also important to consider how you will print. How many replicates do you want Should these replicates be...

The text and CD-ROM provide end users with resource data to develop and improve their quality system without spending a lot of money on consultants or reinventing the wheel. The SOPs are made available in such a form that end users can input them into their computer and use their own Microsoft Word program to edit and print these documents. The contents of the quality manuals are written in simple, precise, and global text in order to be in compliance with the elements of international standard ISO 9001 2000, which replaces the second edition of ISO 9001 1994 together with ISO 9002 (1994) and ISO 9003 (1994). 

This manual takes into account documentation of quality manuals and applicable procedures based on quality elements described in international standard ISO 9001 2000. No other manual in print deals exclusively with the key elements of quality and provides hands-on templates to be tailored to achieve ISO 9000 registration/certification.
