Fully Automatic HPTLC Sample Applicator
HPTLC-Applicator AS30 and Autosampler BS35
The BS 35 autosampler was specially developed for coupling with the AS 30 HPTLC applicator. Both devices together can work as a stand-alone device. However, , it is also possible to create methods on the PC andtransfer them to the AS 30. This is very convenient and incorrect operation isreduced to a minimum. The autosampler is completely controlled by the AS 30. The special thingabout high sample throughput is that an autosampler is recommended. He givesthe operator time for other things. Application and rinsingtake place autonomously through the sample rack, which holds up to 80 samples and a storage bottle with the appropriate washing solution. An acrylic glass rack enables the instruments to be arranged in a space-saving manner, while the autosampler is located below the rack and AS 30. A PTFE capillary takes the sample solution to the AS 30 via a very short route. The sample application is the first and important step in HPTLC analysis. The more accurate the application, the better and reproducible the separation. The HPTLC-Applicator AS30 is a semi-automatic sample application device which fulfils the key requirements for the productivity of HPTLC laboratories. The combination of HPTLC-Applicator AS30 and Autosampler BS35 creates an easy and fully automated workflow. Therefore, together they provide the most professional way for precise sample application.
Key Aspects of Autosampler BS35
Key Aspects of HPTLC-Applicator AS30
With the HPTLC-Applicator AS30 samples are sprayed onto TLC/HPTLCplates with compressed air flow without contacting the plates. The sampleapplication is carried out automatically, only filling and inserting the syringeis made manually. A dosing syringe is fixed at a movable turret. Therefore,removing and new adjusting of this syringe for every application is notnecessary. It can be filled either manually by the filling syringe or by theAutosampler BS35. This is remarkable and time-saving especially whenhaving a high sample-throughput. Up to 80 different samples can be appliedcompletely automatically.The benefit of the spray-on technique for quantitative analysis is the possibilityof applying different volumes of same calibration standard instead of equalvolumes of different standard concentrations. Even if samples are dissolvedin polar solvents such as water, compact and narrow bands are formed.Optional: Special cover with active exhaustion of the aerosols is available formore safety and a clean working atmosphere in the laboratory.
