Now mainly are two typs quantum resonacne magnetic analyzer

2nd generation and 3rd generation quantum analyzer, should distinguish from hardware and software

Hardware:

         2nd generation use solo-core process and 3rd generation quantum analyzer use dual-core process

Software:
 
         2nd generation do not support Win8 system, less accuracy, compatibility and stability, less then 30 report
         
         3rd generation support XP/Vista/Win2K/Win7/Win8 etc. range 85%-90% accuracy with high compatibility and stability

         3rd both children and adult can be checked, new add comparision function, with more than 30 report

PS: some analyzer in the market will use 3rd software but only solo-core process.
    This kind of machine also "3rd generation", actually it is 2nd generation but can't be fixed and upgraded before solo-core less compatibility.
