【求助】EPA7473测试方法的详情有谁知道?请告知!

个人理解，这个方法主要是测试过程控制，
而测汞仪 应该是单独设备，属于方法中的测试设备。
而计算汞浓度，可以是设备直接读出。
12.0 DATA ANALYSIS AND CALCULATIONS
Calculate metal concentrations: (1) by the method of standard addition, (2) from a
calibration curve, or (3) directly from the instrument’s concentration read-out. All dilution or
concentration factors must be taken into account. Concentrations reported for multiphased or wet
samples must be appropriately qualified (e.g., 5 μg/g dry weight)
这只是个人理解，有不对的地方欢迎提出。
