P) content. ICP method will not be addressed here. The potential use of a Corona detector to determine base 4 that is not detected by the UV detector will be discussed. The quantitation of the Cl bases is based on one single predominant peak for each base. We have used an Agilent Model 1200 HPLC instrument and an Acclaim surfactant column (5 pm, 4.6 x 150 mm) to evaluate the method. Typical retention times observed for Cl based on UV detection are 2.4 minutes for base 1, 17.1 minutes for base 2, and 15.2 minutes for base 3. A typical chromatogram is presented in Figure 1. The small peak that tails the predominant peak at 2.43 minutes was included in the calculation of the peak area for base 1. 

Triple quadrupole mass spectrometer using electrospray ionization source, e.g., Agilent Model 6410 or similar (Agilent Technologies). 

The project execution layer is typically controlled by some product development lifecycle model (PDLM). Some PDLMs widely used for software development are the Waterfall model, Spiral model, Agile model and the Unified Process. Due to the large variety of businesses and products within the ABB Group one cannot find one single development life cycle model which is actually being used company-wide. Through the years, each business unit adopted its own approach based not only on the type of product but also on several other factors like market type, country, early company know-how, past experiences, development team culture, etc. 

The sample temperature was set using a special thermostat that could control the temperature in the interval 0-40 °C. In order to prevent the formation of condensate on the sample and electrodes, the entire test fixture (Agilent Model 1645IB) was arranged in a vacuum chamber (Figure 7.4) evacuated by forevacuum pump. The sample temperature was measured by a chromel-alumel thermocouple, one junction of which was fixed with an epoxy glue on the lower electrode, in the immediate vicinity of the sample. The second junction was placed into a water-ice mixture at 0 ° C. The thermo emf in the thermocouple was measured by a digital millivoltmeter.

IH and 13C NMR spectra were recorded on a Bmcker AM-200 and 500MHz) chemical shifts are given in d values referred to internal tetramethlysilane (TMS), EIMS (MS Agilent 5973 70eV) and Infrared (IV) spectra were recorded on a Nicolet spectrophotometer with Fourier transform Model Magna-IR 760 wavelengths are expressed in reciprocal centimeter (cm ). 

Liquid chromatography/mass spectrometry analyses were performed with an ion trap mass spectrometer (LCQ, Thermo Fisher Scientific Inc., MA) equipped with an HPLC system (Agilent, CA Model 1100) connected with a diode-array detector (DAD, G1315A). The sample solution (1-5 p,L) was applied on an Inertsil ODS-3 column (2.1 x 150 mm, 3 p,m, GL... 

We use single-stage quadrupole (typically Agilent bench-top 5971 or 5973MSD) instruments for most applications. The current model offered is the Agilent 5975 (www. agilent.com).

The HPLC analyses were performed on an Agilent Technology Model 1100 HPLC system equipped with a quaternary solvent delivery system, 1100 autosampler. 

In the first spectrophotometric method [22] the measurements were carried out using an Agilent 8453 model UV-Vis spectrophotometer with a DAD. The spectra were recorded from 225 to 475 nm. The quantitative analysis were performed at 376 nm for the zero-order derivative UV spectrophotometric method by measuring the height of the peak from zero and at 302 nm, and 281 nm for the first-order derivative UV... 

A large number of manufacturers make numerous quadrupole mass spectrometer models. A few prominent companies among the many in the field include Agilent, Thermo Finnigan, Waters Micromass, and Applied Biosys-tems/MDS Sciex. Most QMFs are intended primarily for use with separations, such as GC or LC. Nearly any ion source imaginable is marketed with one quadrupole mass spectrometer or another, including El, ESI, APCI, IGF, and others.
