Hardware for Columns

1 Do I need a connector when using the Cartridge Columns that use WVS Hardware?

The WVS (Whatman Void Sealing) cartridge columns use a unique sealing system to ensure compression of the packed bed even if a void develops. All of our WVS cartridge column products require the use of…

2 Do you have 0.5um titanium or PEEK frits available for the PEEK column hardware?

In addition to the standard 5um stainless steel or PEEK frits, we have 0.5um titanium frits available but not in PEEK. PEEK Column Hardware Product Page © Copyright MicroSolv Technology Corporation,…

3 Does MicroSolv offer TYPE-C HPLC columns that do not have PEEK components

Most of our Cogent™ HPLC columns are made with state of the art, column hardware that contains stainless steel frits that are held to the column during manufacturing with caps that are made with high…

4 Guidelines for packing resin (packing material or phase) in the PEEK column hardware.

We do not offer any specific SOP for packing columns in PEEK or Stainless Steel column hardware as every packing material or phase is different and needs to be treated and packed differently. This is…

5 Is PEEK tubing or PEEK fittings autoclavable?

Yes, many scientists have used PEEK successfully when autoclaving PEEK tubing and or PEEK fittings using gamma irradiation, heat or ethylene oxide. PEEK tubing information © Copyright MicroSolv Technology…

6 Solvents and solutions that should be avoided when using PEEK fittings or tubing.

The solvents and chemicals that should be avoided when using PEEK tubing and fittings include: Nitric acid Sulfuric acid Halogenated acids, including hydrofluoric, hydrobromic, and hydroiodic acids Pure…

7 What are the dimensions of your 4.6mm ID 5um PEEK frits?

The frit itself has an outer diameter of 0.188” and a thickness of 0.062”. It is in a PEEK ring with 0.25” O.D. and 0.181” I.D. The frit is press-fit into the ring. PEEK Column Hardware Product…

8 What are the maximum temperature and pressure specifications for the PEEK column hardware?

The PEEK columns can be used for short-term packing at pressures up to 500 bar (see packing protocol) and 300–350 bar under normal long-term operating conditions. You can use the columns at temperatures…

9 What are threading specifications for components of the PEEK columns?

The PEEK column hardware has two specifications for threading: 1. The female outlet threading found on the outside of the endfittings, where the end plugs or extra-column tubing ferrules connect. This…

10 What do WCS and WVS stand for in Partisil™ HPLC columns?

WCS = Whatman Compression Sealing hardware WVS = Whatman Void Sealing hardware Void sealing technology allows for easy adjustment of the frit position to compensate for any voids that develop at the head…

11 What is the largest I.D. for PEEK columns that you offer?

The largest I.D. available is 7.5mm. The corresponding lengths offered for a column of this I.D. are 30, 50, 100, 150, 250, 300 mm. All of these columns are 5/8" O.D. PEEK Hardware Product Page © Copyright…

12 What is the maximum pressure of the PEEK HPLC columns?

The Cogent™ 2.1mm ID column is made of 1/8” tubing.The maximum recommended pressure of the PEEK HPLC column under routine use is 165 bar (2400 psi). However, when packing the stationary phase, a pressure…

13 What is the pH range of PEEK laboratory tubing and fittings?

According the some manufacturers of PEEK, the useful pH range of PEEK tubing and fittings for HPLC is 2 - 14 for use with HPLC solvents and buffers. However, I would be very careful with pH 0 to 6 for…

14 What is the pressure capability of the PEEK column coupler?

The HPLC column couplers (cat# 47450-01, 47450-02, 47450-03, or 47450-04) are standard HPLC items and if installed properly while using standard temperatures and normal HPLC solvents, they should be able…

15 Which size Guard Column should I use with my 1mm, Cogent 2.o column?

The 1mm, 2.o Cogent HPLC Columns™ do not have compatible guard columns so w e recommend our HPLC PreColumn filters. These disposable inline Filters protect the column from un-dissolved particles do…
