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