An HPLC column holding apparatus used to mount an HPLC column in one of a plurality of positions is disclosed herein.

A liquid sample is prepared at a preparation site and then processed, e.g. in an HPLC column.

You need the right HPLC or GC column for your method.

The apparatus comprises a clip-device interface that secures the apparatus to a platform and a clip-column interface that secures the HPLC column to the apparatus.

The osteoinductive proteins can be eluted from the HPLC column with an acetonitrile solution in combination with aqueous trifluoracetic acid.

In the method, the respective samples are passed through an HPLC column (preferably a phenylboronate column) and non-glycated and glycated fractions are separated using appropriate mobile phases.

The presence of polar groups in the stationary phase may seriously impair the performance of the HPLC column.

Pipes, connection elements and connections of this type are advantageously used in low and high pressure systems, such as, for example, in an HPLC column.

The sample is then applied to a MALDI/TOF target or HPLC column and analyzed in a mass spectrometer the presence, absence or variation of the biomarkers.

These might include the type and size of your HPLC column, the buffer or the concentrations of chemicals.

Particulate material (M) located in the cylindrical barrel (10) of an HPLC column is compacted axially and radially to insure a reproducible packing bed uniformity by plunger (138).

The type of sample loading on a flash cartridge or a prep HPLC column has a big impact on the final purification results.

The method comprises analyzing human breast cyst fluid for the presence of a unique factor which has a retention time on an Amino Carbohydrate HPLC column of between about 6.4 minutes and about 6.7 minutes.

An HPLC column holding apparatus used to mount an HPLC column in one of a plurality of positions is disclosed herein.

HPLC dead time (minutes) (see Section 1.8.2).
