What types of matrices are cleaned with double packing columns?
Customer’s detailed question: Are the columns with “double packing volume for additional purification” recommended when using larger extract volumes or when analyzing more complex sample matrices? If they are for larger volumes, what is the recommended volume range? If they are for more complex matrices, what types of matrices should be tested using these columns? How do they compare with the columns for “small” or “average” sample sizes? MycoSep®112 AflaZon and MycoSep®113 Trich columns: These columns are used for “easy” to clean up samples (grains, corn extract, etc.) A small amount of 1 ml of extract is passed through the column. MycoSep®224 AflaZon and MycoSep®225 Trich columns: These columns are used for grains and a maximum of 2ml extract is passed through the column. MycoSep®226 AflaZon+ and MycoSep®227 Trich+ columns: These columns are used for extra clean up; i.e. complex matrices such as finished feeds, etc. A maximum of 4 ml of extract is passed through the column.
