Said sample heater (10) comprises a support (11), a first body means (13) adapted on the support (11), and a second body means (15). The first body means (13) is provided with holes (14) for sample vials, and the second body means (15) is provided with holes (16) for injection needles.

Description

Sample heater
The invention relates to a sample heater to liquefy a sample to be injected, and to keep it in a liquid state throughout the injection step.
For manual injection of samples which are solid at room temperature such sample must be liquefied and kept in a liquid state throughout the injection step.
The object of the present invention is to provide a sample heater which may be placed as close to the site of injection as possible. Another object of the invention is to make a sample heater available to provide in a simple and reliable way feeds to be injected with a viscosity required for injection at temperatures desired.
The objects of the invention are attained with a sample heater which is characterized in that said sample heater comprises a support, a first body means adapted on this support and a second body means, the first body means being provided with holes for sample vials, and the second body means being provided with holes for injection needles.
The sample heater of the invention is suitable for the manual injection of any solid sample that must be liquefied for the injection and kept in a liquid state throughout the injection step. The sample heater of the invention has been tested in micro reactor studies of fluid bed catalysis, and said heater is found very convenient and easy to handle. The heater is placed in the immediate vicinity to the site of injection, and the oil feeds to be injected may be provided with a viscosity required for the injection at the temperatures of 40 and 80°C. Owing to the solution of the invention it is not at all necessary to take the sample to be heated out of the heater during the injection. 2
The invention will now be explained in greater detail below with reference to some preferable embodiments thereof shown in the figures of the accompanying drawings, without wishing to limit the invention solely thereto.
Figure 1 is an axonometric view of a preferable embodiment of the sample heater of the invention.
Figure 2 is a partial view of the sample heater of Figure 1 as seen from above.
Figure 3 is a cross section of the structure of Figure 2.
In Figures 1-3 the sample heater of the invention is generally referred to with the reference number 10. In this embodiment, the sample heater 10 comprises a support 11, a handle 12 to carry it, a first body means 13, and a second body means 14. The first body means 13 is preferably a metal cylinder with borings 14 for sample vials. The second body means 15 is preferably also a metal cylinder with borings 16 for injection needles. To the sample heater 10 may be connected a heating resistance, such as a finger heater, and a control means to heat the sample as close to the site of injection as possible.
In Figure 1 a hole for a finger heater is indicated with reference number 17. The sample heater 10 may of course be used without a heating resistance by heating the sample heater 10 warm enough for instance in an oven before injection. The operation principle of the sample heater 10 is to inject hot sample with a hot injection needle to prevent analysis errors due to the solidification of the sample in the injection step.
In a preferable embodiment of the invention the sample heater 10 is made of two aluminium rods with different diameters, as shown in Figures 2 and 3. In this embodiment the aluminium rod 13 with the greater diameter is provided with two borings 14a for 3 ml sample vials, and four borings 14b for 1,8 ml sample vials. 3
The diameters and depths of the borings, or holes 14a, 14b are such that the contact between the vial and the heater is as intimate as possible.
The aluminium rod 15 with the smaller diameter is provided with borings, or holes 16 sized according to the metal tip of the injection cylinder, the number of the borings being three in this embodiment. As shown in Figure 3, the upper parts 16a of the borings are conically enlarged for the body means of the injection needle, and the lower parts 16b thereof are sized wide enough for the tip of the injection needle.
The body means 13 and 15 of the sample heater are preferably joined together with pressure adaptation, and the heater part 13, 15 is fixed on the support 11 for instance by partly embedding it into the support plate 11, and with screw connection. The first body means 13 is further provided with a connection, or hole 17 for a heating resistance, for instance for a finger heater, and the earth connection of the finger heater is fixed to a fixing screw. A thermoelement of a control means is preferably situated into one of the heating holes 14 of the injection cylinder.
Only some of the preferable embodiments of the invention are described above, and it is clear to those skilled in the art that several modifications thereof are possible without departing from the scope of the invention as defined in the appended claims.
