Abstract:
1. A method of performing a sizing analysis of separated components, the method comprising: providing an archival sizing ladder, the archival sizing ladder including previously measured archival ladder migration times; measuring migration times for a standard sizing ladder through a separation channel in a first fractionation device, the separation channel having a quantity of a first batch of sieving gel disposed therein, thereby providing a first sieving gel sizing ladder, the first sieving gel sizing ladder including first sieving gel ladder migration times; determining a ratio of the first sieving gel sizing ladder migration times to the archival ladder migration times, thereby providing a first correction; encoding the first correction into a first information storage means; attaching the first information storage means to a second fractionation device, a separation channel of the second fractionation device having a quantity of the first batch of sieving gel disposed therein; reading the first correction encoded into the information storage means; applying the first correction to each archival ladder migration time, thereby providing a first corrected archival sizing ladder; and performing a sizing analysis of the separated components of a sample disposed in the second fractionation device using the first corrected archival sizing ladder in comparison with a parameter for at least one of the separated components, the parameter being selected from the group consisting of separated component migration time and separated component band position.
