Liner selection Guide. V5.1
P/No: A100001, Fritted liner, frit on 15 mm
This liner contains a medium porosity glass frit made from sintered, deactivated glass. This liner can be used for hot and cold split and splitless injections. In addition, if used with a suitable packing material the liner can be used for large volume injection, thermal desorption, solid sampling and pyrolysis applications. If packed, a bed depth of up to 25 mm can be employed and retained in place with a plug of deactivated glass or quartz wool. This liner is the most commonly used style. (Pack size is 5)
P/No: A100092, liner for split injections (single necked)
This liner is specially made for hot or cold split injections. The liners large internal diameter of 3.2 mm makes for good mixing of the sample with the carrier gas. The liner may be packed with a little glass wool if desired. The bottom of the liner has a small slot to ensure free passage of gas to the split exit. (Pack size is 5)
P/No: A100127, quartz liner for split injections (single necked)
This liner is identical in design to A100091 one but is made from high purity quartz and offers superior inertness for some applications. Quartz liners are identified by a ring etched around the middle of the liner.(Pack size is 5)
P/No: A100049, Empty liner for splitless injections
This liner is for hot and cold splitless injection of sample volumes below 3µl (best 1µl or less). The narrow internal diameter of 1 mm ensures fast transfer of the sample to the column under splitless conditions. We advise this liner for SPME techniques. (Pack size is 5)
P/No: A100132, Baffled splitless liner
This liner is for hot and cold splitless injection of sample volumes below 3µl (best 1µl or less). The narrow internal diameter of 1 mm ensures fast transfer of the sample to the column under splitless conditions. With this liner the sample is not falling direct onto the bottom of the injector. This liner will give better results for the high boiling components. (Pack size is 5)
P/No: A100128, On-column liner for 0.32mm columns This liner has a small id with a tapered restriction 10 mm from the top. With a column installed into the restriction, true on-column injection can be performed. On-column provides the best possible reference when developing large volume injection methods. Look in manual how to do. (Pack size is 5)
P/No: A100129, On-column liner for 0.53mm columns
This liner is identical to A100128 one but is for use with 0.53 mm id columns. Look in manual how to do. (Pack size is 5)
P/No: L100009, Fritted liner on 20 mm with single taper
This liner contains a medium porosity glass frit made from sintered, deactivated glass. This liner can be used for hot and cold split and splitless injections. In addition, if used with a suitable packing material the liner can be used for large volume injection, thermal desorption, solid sampling and pyrolysis applications. If packed, a bed depth of up to 25 mm can be employed and retained in place with a plug of deactivated glass or quartz wool. The taper will improve the sensitivity for trace, active samples. (Pack size is 5)
Liners for large volume injection
These standard liners have properties that are well understood and provide a reliable solution to the majority of applications. Some are packed with proprietary packing materials which have been especially developed for large volume injection. These liners are denoted by a letter. The use of syringes equipped with dome tipped, side hole needles are strongly recommended. These result in better liner capacity and reduced septum damage.
P/No: A100060, “A” type packed liner for large volume injections
This liner contains a highly deactivated packing which combines a maximum operating temperature of 350°C with a high sample capacity (in excess of 150 µl in most cases). This liner has been found to be suitable for the following classes of compound:
OCl pesticides
OCP pesticides
Triazine herbicides
PAHs
Mineral oils
Derivatised acid herbicides
Drugs of abuse
Do not use in combination with dichloromethane.
(Pack size is 5)
P/No: A100095, “8270” packed liner for large volume injections
This liner contains a highly deactivated packing which combines a maximum operating temperature of 305°C with a high sample capacity (in excess of 150µl in most cases). This liner has been developed for the EPA 8270. Advised needle penetration is 32mm maximum is 32mm. (Pack size is 5)
P/No: A100056, Multi-capillary liner for large volume injection
This liner is both very inert and capable of operation to 600°C. As such it is suitable for the large volume injection of high MW compounds and for compounds which suffer from adsorption. The capacity of the liner is lower than that of a packed liner (25-50 µl, depending upon solvent used). To maximize sample capacity, the liner is best used in combination with a syringe fitted with a dome tipped, side hole needle. This liner is suitable for the following applications:
High MW hydrocarbons
Pyrethroids
OCP pesticides
(Pack size is 5)
P/No: A100133, Sintered glass liner with taper
This liner is both very inert and capable of operation to 600°C. As such it is suitable for the large volume injection of high MW compounds and for compounds which suffer from adsorption. The capacity of the liner is lower than that of a packed liner (about 50 µl, depending upon solvent used). To maximize sample capacity, the liner is best used in combination with a syringe fitted with a dome tipped, side hole needle.(Pack size is 5)
P/No: A100106, At-column liner
This liner is used for the At-column technique. The At-column technique is a rapid large volume technique with the advantages of on-column.(Pack size is 5)
P/No L100011, LINEX DMI Liner
This liner contains 3 small indentations made to hold the microvial in. It is used for Difficult Matrix Introduction (DMI) in combination with L100010 and D100005. This technique extends the capability of OPTIC to the analysis of dirty liquid samples containing non-volatiles and/or solid-like suspended matrix. Row sample or roughly filtered extract placed into a sample container (micro-vial, p/n D100005), which is inserted into the liner. DMI Needle Guide (p/n L100010) is used to ensure an accurate sample injection. Pack size: 5
P/No: D100005, DMI Liner Insert (micro vial)
This is a low cost micro vial and can be used in combination with D100004. In order to have the needle inside the micro vial during injection, the glass needle guide (D100008) has to be used. (Pack size is 100)
Silanisation of liners
Each liner can be ordered with a high pressure silanisation. Ordering:Put an S behind the part number of the liner.
Water and/or temperatures above 300°C will destroy the silanization.
