The Standards Addition Module (SAM) is an option for the Model 4551A Autosampler that automatically adds internal standards or surrogate/matrix spike standards, increasing accuracy and precision of GC or GC/MS analytical methods. Programming of standard addition occurs from two separate and independent 10-mL reservoirs for maximum method flexibility. The SAM module also mounts quickly and easily on the autosampler chassis, saving valuable benchspace.
