Antocyanins were sorbed from the concentrate onto the cartridge sorbent, the cartridge was washed with 1ml of HC1, and anthocyanins were re-extracted by the eluent
containing 30 vol.
The results from 4 repeat linearity experiments for recombinant FXN and CP spiked into DBSs and EDTA-containing blood eluents
as measured with the duplex assay are summarized in Fig.
A was water and eluent
B was acetonitrile--water (95:5), both containing 2 mM ammonium formate and 50 mM formic acid (Quilliam 2003).
The process for purification was as follows: the concentration of sample solution was 500 g/l; adsorption flow rate was 2 BV/h (bed volume/hour); eluent
was 30% ethanol; the dosage was 9 BV; elution flow rate was 1 BV/h.
The column was eluted with toluene, ethyl acetate and acetic acid (50:49:1) and the eluent
collected in volumes of 3.
The benzene eluent
from the column fractionation (the fraction containing aromatics) was examined by establishing the retention index from the literature and standards injection.
For an upgraded system, the EG Eluent
Generator Module supports dual-component eluents
The flow rate, pH, and eluents
greatly affect both the separation efficiency and the treatment capacity of the columns.
The high specificity of the antibody-based biosensor enables the direct quantitation of FLAG-tagged analytes in crude lysates, column eluents
, cell lysates and cell culture supernatants.
1) consists of silica gel powder (230 mesh to 400 mesh with silica gel-to-CLCE ratio of 40 g/g), composition of different eluents
as shown in Table 1 and piston vacuum pump with vacuum pressure of 800 mbar.
