Dogs that spend time at daycares or groomers are often required to have this. The acronyms, DHPP, DHLPP, DA2PP-L, DA2PP-C, often appear on our dogsâ summary report of vaccines. These acronyms stand for a combination of vaccines that protect against serious viruses. DHPP stands for Distemper, Hepatitis, Parvovirus, Parainfluenza. DHLPP is the same as DHPP with the additional vaccine for Leptrospirosis. DA2PP-L stands for Distemper, Adenovirus, Parvovirus, Parainfluenza, and Leptospirosis.
Adsorption is the adhesion of atoms, ions, or molecules from a gas, liquid, or dissolved solid to a surface. This process creates a film of the adsorbate on the surface of the adsorbent.
Elution then is the process of removing analytes from the adsorbent by running a solvent, called an eluent, past the adsorbent/analyte complex. As the solvent molecules elute, or travel down through the chromatography column, they can either pass by the adsorbent/analyte complex or they can displace the analyte by binding to the adsorbent in its place.
