1 The intermittent injection desolvation method is used to accumulate the sample the graphite furnace surface.

2 The similar hydrophobic desolvation free energies indicate that electrostatic interaction energies are very similar among the three coronavirus main proteinase dimers.

3 The intermittent injection desolvation method is used to accumulate the sample onto the graphite furnace surface.

4 Aqucous sample was introduced into MIP using an ultrasonic nebulizer. In present work the desolvation was ashicved by means of a heated tube, a conventional condenser and a concentrated H_2SO_4 cell.

5 OBJECTIVE To optimize the preparation method of albumin nanoparticles by desolvation.
