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.
