Beginning in 2005, Jack Kirkland (1925-2016), founding father of the porous-shell technology, joined Advanced Materials Technology, Inc..
"These particles were commercialized by DuPont as Zipax in 1968 and Permaphase in 1970. With the development of the much smaller and more efficient porous silica microspheres such as Zorbax in the early 1970s, the larger Zipax particles quickly lost favor. More than 20 years passed before there was a rebirth of SPP" (LCGC Eur., vol.26, issue 8).
AMT is #1 worldwide manufacturer for Fused-Core silica particles (Halo family).
These particles bring critical improvements that resulted in the prominence of HPLC superficially porous particles today.

Halo family
|
- Halo superficially porous particles from 5 to 2 µm.
- Biochromatography is a very promising field as Fused-Core particles provides narrower peaks and better recoveries for large biomolecules (vs. smaller pore sizes and non-core particles). AMT manufactures SPP up to 1000 Angstroms pores to provide unrestricted pore access for polypeptides, proteins and Monoclonal Antibodies (Halo Protein, Halo Peptide, Halo Glycan).
