Knitted Reactor Coils

1 Are the Knitted Reactor Coils compatible with the Post Column Photolytic Reactor? Will bubbles form during use?

The Knitted Reactor Coils are especially designed to fit into the Post Column Photolytic Reactor (cat# 49900-01) and their material of construction (PTFE) is transparent to the 254 nm UV light. Bubble…

2 Are there any solvents that I cannot use with the knitted reactor coils (KRC) and knitted delay tubes (KDT)?

Yes, you cannot use any perfluorinated solvents or any solvent not compatible with PTFE with the KRC and KDT. Click here to learn more about the post column reactor Click here to learn more about knitted…

3 Can the Knitted Reactor Coil (KRC) be used with a standard HPLC pump?

The unit typically generates around 600 psi, which of course can varying depending on solvent viscosity and so forth. Therefore, the unit is fully compatible with a standard HPLC pump. Knitted Reactor…

4 Can the knitted reactor coils (KRC) be heated or cooled?

Yes, you can use one of the MicroSolv HPLC Column Water Jackets and pump heated or cooled liquid through it. The maximum temperature that the KRC or KDT can withstand is 200°C Click here to learn more…

5 Do you have suggestions for a knitted reactor coils with a volume of 0.375ml with an internal diameter of 0.5mm?

A 1meter long coil with 0.5 mm ID has a volume of 196 µl. therefore you would need 1.9 meter long coil. As we do not offer a reaction coil with such length needed for 375µl volume, I suggest you purchase…

6 How can I change the reaction time of the knitted reactor coils (KRC)?

The reaction time can be changed by changing the inner diameter and length of the KRC. Click here to learn more about the post column reactor Click here to learn more about knitted reactor coils © Copyright…

7 How to use Knitted Delay Tubes (KDTs) in mass directed prep chromatography

According to the International Journal of Mass Spectrometry, Knitted Delay Tubes can be used in the following manner with mass directed prep chromatography: Due to the low flow reaching the MS after the…

8 I have been using the photochemical reactor for a while now. Is there a decrease in the pressure rating of the KRC?

Yes, with long term or constant use there is a natural decrease in the pressure rating and the knitted reactor coil should be replaced. Click here to learn more about the post column reactor Click here…

9 I want to use the post column photochemical reactor for Aflotxins. Which knitted reactor coil (KRC) do you recommend? What other accessories would I need?

The recommended KRC for Aflatoxin analysis is the 49900-KRC2525, 1.25ml void volume. The uv lamp supplied in the Photochemical Reactor is a low pressure mercury with 254nm light and is purchased with…

10 Is a knitted reactor coil (KRC) included in the purchase of the photochemical reactor?

No, you can select from one of 1 many coils that will be completely compatible with the photochemical reactor. They vary in length and ID. See link below. Click here to learn more about the post column…

12 What are the knitted reactor coils (KRC) made from?

The knitted reactor coils are made of virgin, medical grade PTFE (a form of Teflon). Click here to learn more about the post column reactor Click here to learn more about knitted reactor coils © Copyright…

13 What is the best way to attach the inlet of the knitted reactor coil tubing to the outlet of a tee with a PEEK finger tight fitting that will hold high back pressure?

Confirm that there is not an impediment to reasonable flow through the tubing which could increase the back pressure. We recommend using our items 47320-30 and 47320-34 which are High pressure Male nuts…

14 What is the pressure rating of the knitted reactor coils (KRC) used with the post column reactor?

The knitted reactor coils are rated to hold 300 psig. After time and extended use, this rating may be significantly reduced. Click here to learn more about the post column reactor Click here to learn…

15 What maximum flow rate can I use for a PTFE, 10m, 0.75mm ID Knitted Reactor Coil (KRC) with isopropanol?

Question: I am using a PTFE Knitted Reactor Coil (KRC) with 10m length and 0.75mm ID with isopropanol as the fluid I am pumping. What is the maximum flow rate I can use under these conditions? Answer:…
