Table 4 on page 35 of EPA Method 524.3 lists the target compounds, the internal standard compound each is associated with, and a recommended quant ion. The technique is also useful if you are converting an external standard calibration to an internal standard calibration (for example, 8081) to avoid the closing calibration verification requirements. Your compound lists and analytical columns will see little to no change, but your internal standard and surrogate compounds may be different. This technique is particularly useful if your lab is expanding the tests offered from hazardous waste (series 8000 methods) to waste water (series 600).

I will be using the 524.3 list as an example. The first request I'm going to address is how to add or change internal standard and surrogate compounds in a calibration using Enviroquant and Enhanced Chemstation, and how to configure the software to automatically calculate concentrations and surrogate percent recoveries using the internal standards. Be forewarned my experience is limited to Enviroquant and Enhanced ChemStation. I will primarily be working in the most current version of MSD ChemStation that I have: G1701EA.02.02, though I can offer help with AA.03, BA.00, and various DA and EA versions of the software. Feel free to leave requests in the comments if there's something you need help with. I've decided to start a blog series to address these requests. Our technical service department receives quite a few MSD ChemStation software functionality related requests which are frequently forwarded to me.
