The debate is whether a blank or Zero point should be run as calibration standard one. The way things have always been is to run a blank as calibration standard 1 and then follow with our normal standards. With the purchase of some new instrumentation, the company has said a zero point is not necessary, and not a good practice to do. The methods we run are EPA 9056 and 300.0. The way the methods are written leaves the argument open for debate. I am wondering what the community here thinks.
