Vial for chromatography
The cylindrical glass vial with extended lower part server first of all to perform a simple verification of radiochemical purity of radiopharmaceuticals using the method of upward chromatography on a paper and thin layers.
The lower part of the vial is filled with a proper volume of developing agent (about 10 mm high). The chromatogram is to be placed into the vial after depositing the sample an the start using the Pad for Chromatography type PT 298 R0. The enlargement of the lower part of the vial disables a direct contact of the chromatogram and the vial thus excluding the one-sided capillary action and the distortion of the mobile phase movement.
It is generally more simple to make the chromatography in two systems cutting the chromatogram into two pieces than to use the system with cutting into more peaces. It is also possible considering the way of the measuring the activity to simplify the manipulation by leaving out the drying of the chromatogram. The wet chromatogram is to be cut at the marked spot and the pieces subsequently let fall into the measuring vial and measure.
