UPLC Columns

USHD UPLC Columns

The selection sheet lists USHD reversed-phase, HILIC, normal-phase, phenyl, PFP, and SEC columns for UPLC / UHPLC. Tables below follow that sheet: phase, particle size, pore size, and catalog number.

1.7 μm is only 1.0 mm ID. 1.8 μm and 2.5 μm are the other sub-2 μm sizes. 3 μm, 3.5 μm, and 5 μm are listed on the same sheet. Most pores are 120 Å. C18-Pro and C8-Pro are 150 Å. ZIL 5 μm is 100 Å. The bio columns include 300 Å.

Features

One selection sheet for the UPLC / UHPLC columns: reversed phase, HILIC, normal phase, phenyl, PFP, and SEC.

1.7 μm on 1.0 mm1.8 μm and 2.5 μm3 μm and 3.5 μm5 μm120 Å, 150 Å, 300 Å100 Å ZIL 5 μm

1.0 mm ID is its own group — Ten columns, all 1.7 μm and 120 Å, all 1.0×50 mm or 1.0×100 mm. Phases are C18, C18-AQ, C18-AR, C18-T, and C8.
Sub-2 μm analytical hardware — 1.8 μm, and 2.5 μm on HILIC-Amide and HILIC-ZIL. Inner diameters are 2.1 mm, 3.0 mm, and 4.6 mm. The longest 1.8 μm column on the sheet is 4.6×100 mm.
3 μm, 3.5 μm, and 5 μm — Same phases, larger particles. 3.5 μm appears only on C18-Pro and C8-Pro, both 150 Å. 5 μm is the only particle size for SiO2, CN, and NH2.
SEC at the end of the sheet — SEC-Bio in 4.6×300 and 7.8×300 mm, then C8-Bio and C4-Bio at 5 μm, 300 Å.

Applications

Uses already described for these phases on the current column pages.

Small-molecule reversed phase

C18, C18-AQ, C18-AR, C18-T, C8, and C30 for pharmaceutical, food, and environmental methods. AQ when the mobile phase is mostly water. AR at low pH. T when the method goes alkaline.

Selectivity other than C18

Phenyl for aromatic compounds. PFP for aromatics, halogenated compounds, and basic analytes. CN when the method can run normal or reversed phase.

Polar and biomolecule work

HILIC-SiO2, HILIC-Amide, and HILIC-ZIL for polar metabolites. NH2 for sugars. SEC-Bio, C8-Bio, and C4-Bio for larger biomolecules.

1.7 μm versus 1.8 μm

1.7 μm is the 1.0 mm ID pair. 1.8 μm starts at 2.1 mm ID. They are not interchangeable hardware.

Phase confirmation

C18-Pro and C8-Pro are the 150 Å phases. The other reversed-phase blocks on this sheet are 120 Å, except the 300 Å bio columns and the 100 Å ZIL 5 μm block.

FAQ

How the sheet is organized, and where it differs from the older UPLC cards.

01How is this UPLC list split?

The sheet is one 超高压色谱柱 list. It is grouped here by phase, then by particle size. 1.7 μm is only the 1.0×50 mm and 1.0×100 mm columns. 1.8 μm and 2.5 μm are the other sub-2 μm sizes, on 2.1 mm, 3.0 mm, and 4.6 mm hardware. 3 μm, 3.5 μm, and 5 μm are the larger-particle columns on the same sheet. SEC-Bio also has 7.8×300 mm.

02What is the 1.7 μm column?

USHD C18, C18-AQ, C18-AR, C18-T, and C8 each list two 1.7 μm, 120 Å columns: 1.0×50 mm and 1.0×100 mm. No other inner diameter is printed at 1.7 μm.

03Which pore sizes are on the sheet?

Most phases are 120 Å. C18-Pro and C8-Pro are 150 Å. HILIC-ZIL 5 μm is 100 Å. SEC-Bio is 120 Å or 300 Å. C8-Bio and C4-Bio on this sheet are 300 Å. The 5 μm SEC-Bio pair is one 120 Å set and one 300 Å set.

04Where is ValuSil C18?

This sheet lists ValuSil C18, 5 μm, 120 Å, as P1F0B-00903 (4.6×150 mm) and P1F0B-00904 (4.6×250 mm). The ValuSil product page has the wider 1.8 μm and 3 μm set.

05Are the PFP, SiO2, and CN numbers the same as the other pages?

Yes. USHD PFP 5 μm and 3 μm, USHD SiO2 5 μm, and USHD CN 5 μm match the catalog numbers already published on those product pages. On this sheet, HILIC-Amide 2.5 μm, 2.1×50 mm is P1F0B-00817, and P1F0B-00819 is HILIC-Amide 1.8 μm, 2.1×50 mm. The HILIC column page also lists 00819 as 2.5 μm, 2.1×50 mm. Confirm that pair before ordering.

06What did the old UPLC cards claim that this sheet does not?

The previous cards mixed 150 Å into C18 and C8, and listed 1.8 μm on phases where this sheet has no 1.8 μm row. C8-Pro on the sheet is 5 μm and 3.5 μm at 150 Å. Those older card lines are not in the catalog tables.
