The fully automated DBS-MS 500 from CAMAG is state of the art technology to analyze DBS. The DBS are directly eluted in a designed extraction chamber and guided online to an analysis system. Sample processing is automated, including the application of an internal standard through a high precision sprayer and barcode assignment. In addition to the analysis results, a picture of each DBS card before and after extraction and the run parameters are reported to maintain high traceability and quality.
- High throughput analysis of up to 500 DBS cards per run
- Integrated optical card recognition and barcode reading module
- Automated internal standard application module
- Unique extraction module with wash station to eliminate carry-over
- Online coupling to analysis system (LC-MS, MS or Sample Collector)
- Full control through Chronos software
The fully automated CAMAG DBS-MS extraction system makes DBS analysis remarkably easy and has strong advantages compared to both the manual and semi-automated punching techniques. With the CAMAG DBS-MS 500 extraction procedure DBS analysis is an economical alternative to conventional blood sampling. It represents a time- and cost-saving technique for analyzing Pharmacological samples and is less invasive for participants or animals.
Highly reliable robotics handles the DBS cards from 5 separate racks, each with a capacity of 100 cards. The gripping tool picks up cards and moves them to all of the subsequent processes in the corresponding modules and back into their original position after the extraction. All DBS cards in the standard format of 84.67 mm × 53.2 mm can be used, independent of the brand.
2) Optical card recognition
The spot number and position, checkbox status, and barcode information are determined by a camera module with integrated firmware and adapted sensors. The connection between a DBS and its barcode is ensured throughout the whole process. CAMAG has incorporated its know-how of more than a decade of optical HPTLC image analysis to build this precise and reliable camera module.
3) Internal standard application
The extraction efficiency and analysis quality is ensured via the application of an internal standard prior to the extraction. The internal standard solution is applied with a high a precision sprayer onto the DBS. CAMAG has been manufacturing high precision application instruments for HPTLC for a long time and has used this experience to build this module.
4) Extraction Module
The extraction unit seals the DBS card and solvent is guided horizontally through the DBS into a sample loop. The loop volume can be of various sizes and configurations according to the application. The extract is guided online to the analysis system and is independent from the extraction solvent cycle.
5) Wash Station
A designated wash station cleans all parts that are in contact with the DBS cards and additionally flushes the entire tubing to avoid any carry-over. Using this system, independent user tests confirm that carry-over is not an issue.
6) Master Control Software Chronos
Chronos is a sophisticated master software that manages your analytical system in addition to controlling the DBS-MS 500. Sample lists are programmed in Chronos, where sample processing, extraction and analysis parameters are brought together. Chronos is compatible with the majority of common mass spectrometers and allows data exchange between those programs.
Optimization for high throughput
An overlap of workflows is Chronos’ core feature. The software measures the time for each work step in real-time and adapts the sample schedule accordingly even while an analysis is still ongoing. This enables the DBS-MS 500 to prepare the next sample in time and therefore avoid delays due to idle time. As a result Chronos increases the active measuring time of the devices and considerably raises the efficiency of the laboratory.
Real-time analysis monitoring
The sample schedule is visualized in a chart which can be monitored in real-time.
A) Transport the DBS card
B) Optical card recognition
C) Application of internal standard
E) Rinsing the extraction unit
F) Estimated LC-MS cycle time
Robustness and repeatability
The user can create methods with almost no limitations on parameter options. Sample lists can be generated fast and adapted to individual needs for the standard user. Robustness and reproducibility is thus ensured through software controlled automation of the complete analysis.
Chronos not only controls your analytical system, it also reports a 2D barcode, the run parameters of your analytical system and pictures of each DBS card. The 2D barcode automatically assigned to each DBS simplifies handling and avoids errors which might be caused by manual working steps. Thus Chronos ensures traceability of every sample supporting a good documentation practice.
