  2. Agilent Chemstation Calibration Curve

I am working with Agilent Chemstation and am trying to analyze for 3 compounds. I have created an 8 point calibration curve and have a good linear regression for each compound. My calibration curve ranges from 0.05 ug/ml to 10.0 ug/ml. The ChemStation System is a combination of two components: custom-formulated, environmentally friendly industrial cleaning and process chemicalsdelivered to refillable containers directly at your facility. It’s REFILLNOT LANDFILL® and it has remained the same since 1977. Being “green” is.

3.2 Clean the instrument with a clean dry cloth every day. A wet cloth dipped In dilute soap solution may be used occasionally. 3.3 Precaution must be taken to clean the instrument immediately with dry Cloth after wet cleaning. 4.0 PROCEDURE (OPERATION) 4.1 Ensure that the HPLC system is placed in a clean and dust free area. 4.2 Ensure that instrument have been connected to the main power unit.

4.3 Switch ‘ON’ the Computer. 4.4 Switch ‘ON’ the HPLC instrument. (Switch on the detector, column compartment, Pump and vacuum degasser simultaneously). 4.5 Ensure that the outlet from the detector dips into a waste bottle.

5.0 Start the Open Lab Chemistration by double-clicking the Short cute Open Lab Chemistration located on your desktop. 5.1 Click on Open Lab Chemistration online. 5.2 Then click on ‘on’ option.

5.3 Initialization process of HPLC system will be start which shows by yellow colour. 5.4 Green colour and ‘Ready’ indication will be appearing on screen after the Initialization process. 5.5 Click on set up- pump, feed the flow rate NMT 4%,% of solvent and then start the purging by rotating the purge wall in anticlockwise direction approx 10 minute. 5.6 Then ‘OFF’ the Purging by rotating the purge valve in clockwise direction.

Make sure the sample to be run is properly loaded in the auto sampler your instrument. 5.7 Start an instrument application an Instrument Wizard will appear. This wizard is designed direct to the basic functions of the instrument.

5.8 Create or modify a method This button starts the Method Wizard that will enable you to step through creating or modifying a method. 5.9 When you start the Method Wizard, click to create a new method the wizard will Guide you through the method sections. For each section, enter the run Parameters Required for the sample you will be injecting 5.10 Data acquisition and instrument control parameters – (a) Instrument Setup. Select each tab and enter the correct parameters for running this sample (b) Integration events. Additional integration events are not necessary for a test Sample.

Some of the feedback I received after my last post was that most of the small environmental labs out there are still running 5971 and 5972 MSDs off the old G1701AA.03 software, and that demonstrating data processing techniques in G1701EA.02 may not be relevant. Fortunately, we still have a 5890/5971 in the lab.

Unfortunately, we are controlling this instrument from an old computer running Windows NT 4.0 and MSD ChemStation G1701BA.00. In order to demonstrate A.03 functionality, I had to run down a working copy of Windows 98 and install it in a virtual computer in Windows 7 because G1701AA.03 requires a 16 bit version of Windows. Officially, HP only supported Windows 95, but Windows 98 Second Edition was an extremely stable OS, and my old lab had good luck running the software on this platform.

Today’s tutorial will focus exclusively on the EnviroQuant version of A.03, and will cover populating the calibration table with compounds using a few compounds from the first internal standard group of EPA Method 524.3. We will deal exclusively with the initial calibration menu (InitCal) which is shown below, though “save method” is found under the File menu.

First, you will want to set your calibration’s global parameters, and this is done under the “Set Up Quantitation” menu option. There are a few things worth mentioning here. The default integration parameter file is events.e; you can create specific integration parameters for specific compounds, but you’ll want to enter your default integration file here so you don’t need to type it in for every compound later. The same goes for the rest of information in the New Compound Info box below.

Once you are satisfied with your selections for the Quant Database Globals, click enter, and the Edit Compounds dialog box should appear.

Click “Insert Above” and this brings up the “Quant Setup” interface (shown below), where you can select peaks by double right clicking them, name them, and select quant and qualifier ions. Personally, I don’t like this interface, and prefer manually entering the compound info. Generally, I deal with large compounds lists (like 8260 or 8270) and find the peak selection process tedious.

If you go back to InitCal menu, and select “Edit Compounds,” the same Edit Compounds dialog box from before appears, but this time, when you click “Insert Above,” you should see the first page of the compound info screen. If you already know the elution order of your compounds, you can enter them one at a time.

EPA Method 524.3 – Table 4 lists the recommended quantitation ion and associated internal standard (IS) for each of the target analytes. Make sure you change the Quant signal to “Target Ion.” If you don’t know what qualifiers to use, you can look up the EI mass spectra at the NIST website.

Generally, when choosing quantitation and qualification ions, you will want to use the M+ molecular ion, the C13 isotope (M+1)+ or halogen isotope (M+2)+, as well as an ion that can be explained by a common mechanism, such as the loss of a ring, halogen, or hydrogen. The mass fragment with the highest response does not always make the best quantitation ion, especially if it has a relatively low m/z (less than 50) because there is commonly high background responses for these ions.

This is a good stopping point. Next time, we’ll configure internal standards, matrix spike compounds, and surrogates for automated data processing by the quant macro.
