Ngokwamukela izinzwa zokulinganisa ezinembayo kakhulu kanye nama-algorithm okukhokhela isisindo esinamandla, kufeza ukulinganisa okunamandla kwemikhiqizo ku-inthanethi, kuthola ngokunembayo izinkinga ezifana nokuba nesisindo esiningi nesincane kakhulu. Ifanele ukuhlola isisindo somkhiqizo oyedwa noma iqoqo ezimbonini zokudla, zamakhemikhali ansuku zonke, ezamathuluzi nezinye izimboni, ngokunemba kokulinganisa okungu-±0.1g, ingaxhunyaniswa nemishini yokuhlunga ukuze kufezeke ukulahlwa okuzenzakalelayo kwemikhiqizo enesici.
