A capillary electrophoresis systems Agilent CE 1100 (HP, USA) equipped with a diode array detector was used to separate and quantify... 

Esi-ms measurements were performed on a Agilent LC M,SD system with the following operational parameters capillary voltage 4.0 kV, cone voltage, 50 V and solvent flow (methanol - water, 50% v/v) 0.3 inL/min. All esi mass specttal data in the positive ion mode were acquired and processed using HP Chem.Station software. The concenttation of aluminum was 0.5 mmol dm while that of mfx were varied in the interval 0.5-1.0 mmol dm. The pH values were pH 4.0, 6.0, 7.2 and 8.5. The specttum obtained at A1 to mfx concenttation ratio 1 2 and pH 4.0 is shown in Fig. 1. 

The author wishes to acknowledge the efforts of his various research students from whose work some of the applications presented here have been drawn. In particular, I have enjoyed the excellent partnership in the pioneering PhD research of Mr (now Dr) Russell Kinghom. In addition, the provision of a gas chromatograph by Agilent Technologies and columns from SGE International have enabled our work to progress. 

There are many protocols and different types of platforms available, e.g. GeneChips from Affymetrix, Illumina Bead Arrays, Arrays from Agilent, Applied Biosystems, GE Healthcare, customized spotted cDNA microarrays etc. the basic procedure for a large-scale measurement of gene expression involves the preparation of total or mRNA from the biological sample(s) under investigation (e.g. candidate tissue) and the hybridization of copied labelled RNA or cDNA to the DNA elements on the array surface (Fig. 1). 

GC analysis indicated that the reaction was complete. Gas chromatographic analyses were performed on a Agilent 6890N GC system equipped with a 30-m 5% polyphenyl methyl siloxane capillary column...

Despite its weaknesses (such as described in the 1975 collection of essays The Mythical Man Month [11]), the traditional software development life cycle (collect requirements, design, implement, test, deploy, maintain) has remained the standard framework for software development. However, in recent years it has become clear that the life cycle is not well suited to applications that are experimental in nature (i.e., where there is no precedent for the particular kind of application) or that exist in rapidly changing environments. This has led to the development of agile methodologies (also known as lightweight... 

The product stream was separated using a cold trap maintained at 5°C and the the composition of dry reformed gas was analyzed by a gas chromatograph (Agilent 6890N).

The chip micro reactor ([R 6]) was only one part of a complex serial-screening apparatus [20]. This automated system consists of an autosampler (CTC-HTS Pal system) which introduces the reactant solutions in the chip via capillaries. A pumping system (p-HPLC-CEC System) serves for fluid motion by hydro dynamic-driven flow. A dilution system [Jasco PU-15(5)] is used for slug dilution on-chip. The detection system was a Jasco UV-1575 and analysis was carried out by LC/MS (Agilent 1100 series capLC-Waters Micromass ZQ). All components were on-line and self-configured. 

Inject an aliquot of the sample solution into the gas chromatograph. An Agilent 6890 Series gas chromatograph fitted with a 5973 Series mass-selective detector has been found to be suitable for this analysis.
