In a nutshell

The key to quality and reproducibility

The Automatic TLC Sampler 4 initiates the HPTLC process by applying samples, which plays a crucial role in determining analysis quality. Additionally, automation enhances productivity, making the HPTLC lab more efficient. Designed for routine operations and high throughput, the ATS 4 efficiently handles both qualitative and quantitative analyses, as well as preparative separations.

Specifically, the Automatic TLC Sampler 4 applies samples as bands, spots, or rectangles using the spray-on technique. It precisely delivers large volumes and concentrates rectangles into narrow bands with a high-strength elution solvent before chromatography.

Furthermore, the ATS 4 supports “overspotting,” sequentially applying samples onto the same position. This feature proves particularly useful for pre-chromatographic derivatization, spiking, and other similar procedures, enhancing its versatility for a range of applications.

SOFTWARE INTEGRATION

OPERATION WITH VISIONCATS Software

Accurate sample application is essential for achieving high-quality HPTLC analysis. When paired with visionCATS HPTLC software, the ATS 4 enables fully automated sample application, optimized for routine use and high sample throughput.

The instrument parameters dialog box provides user-friendly default settings. For example, selecting a solvent similar to the one in use allows the software to automatically adjust instrument settings based on viscosity, volatility, and surface tension. Additionally, the filling/rinsing process, which controls syringe rinsing frequency and filling repetition, can be customized for specific tasks.

How the ATS 4 works

CAMAG AUTOMATIC TLC SAMPLER 4_septum punch

An application sequence begins with sample uptake. The vial septum is punctured, and the needle is inserted into the sample vial through the puncture. The syringe is then filled with the sample solution.

CAMAG AUTOMATIC TLC SAMPLER 4_septum punch retraction

The septum punch retracts, ensuring that the tightly sealed septum wipes off the exterior of the needle.

CAMAG AUTOMATIC TLC SAMPLER 4_pre-dosage

Before the first application from a newly filled syringe, a small sample volume is pre-dosed onto a waste plate to ensure consistent conditions at the needle tip. This pre-dosage is performed in the same manner as sample application, either through contact spotting or the spray-on technique.

The syringe moves to the programmed position of the plate and starts application of the desired sample volume. If several applications of the same sample have been programmed, these are applied in sequence from the same syringe filling, provided the remaining volume is sufficient. Otherwise, the syringe is automatically refilled.

CAMAG AUTOMATIC TLC SAMPLER 4_syringe emptied

After the final sample application, the syringe is emptied into the waste bottle.

CAMAG AUTOMATIC TLC SAMPLER 4_solvent emptied

The syringe is filled with rinsing solvent, and the plunger moves beyond the side connection to remove any excess solvent. Once the rinsing solvent is emptied into the waste bottle, the dosing system is prepared for the next application sequence.
