Pharm PAC Methods

The methods delivered with the Pharm PAC package can easily be loaded into the following Metrohm Titrino models:

• With the 798 MPT Titrino and 799 GPT Titrino (also applies to 751 GPD Titrino with instrument program version 5.751.0020 or higher and 785 DMP Titrino) you use the methods memory card included in the package to load methods into the Titrino.
  
• With 794 Basic Titrino (also applies to 716 DMS Titrino, 736 GP Titrino and 751 GPD Titrino with instrument program version earlier than 5.751.0020) you use a PC and the demo version of Metrodata VESUV 3.0 contained in the package.

Or load the methods directly into a Titrando and let the method converter transform the methods for you.
