OI Analytical Standards Addition Module


Standards Addition Module

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.


  • Automatically adds internal standard or surrogate/matrix spike standards at operator-defined intervals 
  • Sample sweeps the internal standard or surrogate into the purge-and-trap sparge vessel 
  • Saves benchspace by mounting on the Model 4551A Autosampler or AMPS 
  • Automatically drains excess standard to waste 
  • Uses minimal standard volumes (35–40 µL/sample) 
  • Internal pressure regulator assures consistent transfer and minimal loss 
  • Conveniently located prime keys 
  • Maximum flexibility with two separate 10-mL reservoirs
