TIC) for each urine sample. For comparison of TICs, Agilent ChemStation software allows one easily to stack (overlay) several chromatograms in the same computer window (Fig. 2.2). This feature helps to identify compounds with common retention times among several samples, but does not contain any mass spectral data for verification of a common identity for these peaks and is most useful for comparison of only a few TICs or a few compounds of interest. In these cases, mass spectral comparisons can be made quickly by visual inspection of the relevant spectra.

HPLC/DAD/ESI-MS/MS analyses LC/ESI-MS/MS experiments were performed on Agilent 1100 LC/MSD Trap-SL mass spectrometer (Palo Alto, CA) equipped with an electrospray ionization (ESI) interface, 1100 HPLC, a DAD detector and Chemstation software (Rev.A.09.01). Anthocyanins were monitored at 520 nm. The colunrn used was a 150 cm x 2.0 mm i.d., 4 pm... 

Data collection was performed with Agilents GC ChemStation software revision A.06.03. Although ChemStation software is in-use at DuPont, the MARS units typically used more traditional Laboratory Information Management Systems (LIMS) for GC data management. 

A Hewlett Packard Vectra Pentium IV personal computer operating under Microsoft Windows NT 4.0 and Agilent Technologies A.07.01 ChemStation software was used for data acquisition and instrument control. Two dimension plots were obtained with Fortner Software Transform Version 3.4 after the signal files were exported in CSV file format by the ChemStation software. 

The gradient run was set at 100% A from 0 to 8 min, then to 100% B until 14.5 min, where it held until minute 17. The system reequilibration was performed by changing to 100% A from minute 17 to 18 and remaining with 100% A until minute 20. All operations and data analysis were processed by the Chemstation software v.8.03 (Agilent Technologies, Inc., Santa Clara, CA). 

Agilent ChemStation is a well-proven and a popular software product. Over the years, the software has achieved a high degree of distribution, particularly at universities and public institutions. The software design of ChemStation has become out-of-date over the years. That s why Agilent has started a redesign, calling the software now OpenLAB.

Figure 4.11 Quantitative analysis software for chromatography. Since the signal from the detector situated at the outlet of the column is analogical, an analogue-digital converter (ADC) is necessary. The stored chromatogram, digitized, serves as a basis for its exploitation hy the software. Different zones of the screen can display the calibration curve, methodology, etc. (software Chemstation from Agilent Technologies).

In 2010, Agilent started launching rtgi/ewt OpenLAB CDS. Agilent talks about an evolution of its software instead of calling it a new CDS. Two versions are currently available on the market the ChemStation and the EZchrom edition. Both of them use the same control panel module and the same report generator. All other software parts are adjusted to the customs of ChemStation and EZchrom, respectively. 

Agilent has obtained the EZchrom software with the acquisition of Scientic Software. Over the years, EZchrom has become the core part of many other CDS. Just as ChemStation, the EZchrom software has been revised and is called OpenLAB CDS EZchrom Edition.
