ZirChrom®-PBD
columns do not have to be replaced due to phase loss nearly as often as conventional
silica based columns. |
|
ZirChrom®-PBD columns
are much more pH stable than silica based bonded phases. ZirChrom®-PBD columns
can be used at both low pH (1M nitric acid) and high pH (1M hydroxide) without the active
stationary phase loss characteristic of silica based phases. |
| 2. |
ZirChrom®-PBD
columns do not have to be replaced due to loss in resolution due to changes in peak shape
nearly as often as conventional silica based columns. |
|
ZirChrom®-PBD columns
show no peak tailing for amines (due to silanophilic interactions) over time as do most
silica based phases. |
| 3. |
ZirChrom®-PBD
columns are more efficient than polymer phases. |
| 4. |
ZirChrom®-PBD
columns allow for simplified method development. |
|
ZirChrom®-PBD columns
have a chromatographic selectivity much closer to that of bonded phase silicas than do
polymer type phases thereby greatly simplifying method development. |
| 5. |
ZirChrom®-PBD
columns significantly reduce total analysis costs by decreasing operator time, equipment
run time, organic solvent usage and waste disposal. |
|
ZirChrom®-PBD columns
can be used at much higher temperatures than either silica or polymer based phases. High
temperature analyses are ordinarily much faster than conventional runs. |
| 6. |
ZirChrom®-PBD
columns offer a third dimension (temperature) to optimize band spacing. |
|
ZirChrom®-PBD columns
can be used at high temperature (up to 200°C) thereby allowing the user a third dimension
in LC (along with mobile phase and stationary phase choice) to optimize band
spacing. |
| 7. |
ZirChrom®-PBD
columns eliminate the need for ion pairing agents with attendant poor efficiency. |
|
ZirChrom®-PBD columns
can be used at low and high pH to convert ionized acids (COO-) and bases (NH3+,
etc.) into neutral species thereby avoiding use of ion pairing agents. |
| 8. |
ZirChrom®-CARB
columns are an ideal choice for RPLC when ODS type phases don’t work. |
|
ZirChrom®-CARB columns
are acid, base and temperature stable, offering RPLC behavior with greatly different
chromatographic selectivity compared to conventional silica RPLC phases. ZirChrom®-CARB
columns are generally preferable to conventional alkyl phases for separation of polar and
non-polar isomers (ortho/meta/para, cis/trans, diastereomers). |
| 9. |
ZirChrom®-WAX,
ZirChrom®-SAX and ZirChrom®-SHAX columns are stable (compared to
silica technology) and highly efficient (compared to polymer technology) weak, strong and
strong hydrophilic cross-linked anion exchangers, respectively. ZirChrom®-WCX
is a weak bio-compatible cation-exchanger that is a good alternative to hydroxyapatite. |
| 10. |
ZirChrom®-PHASE
is an uncoated normal phase zirconia support that can be cleaned by removing contaminants
with hot 1M nitric acid. |
