MASTER DHS Dynamic Headspace Sampler
The most appropriate and sensitive sampling solution.
The DANI MASTER DHS system provides the headspace sampling of liquid or solid matrices, located in a sealed and thermostatted vial, through the constant sweeping of the volatiles by a flow of carrier gas.
The use of a dual-needle design enables to transfer the volatiles to a narrow-bore packed trap filled with one or more sorbent materials, and kept at low temperature. After refocusing the volatiles, the trap is heated and the compounds are introduced, by means of a heated transfer line, directly into the GC injection port. In addition, by simply exchanging the needle the MASTER DHS can be operated in Purge & Trap mode.
The volatiles present in the headspace are purged by an inert gas flow, efficiently trapped, refocused and subsequently injected into the GC injection port.
The combination of the MASTER DHS to the MASTER AS Automatic Sampler, a robotic X-Y-Z coordinate sampler, provides precise and accurate sampling, increasing sample throughput and improving analysis performance.
Superior sensitivity is obtained through the constant sweeping of the thermostatted sample, promoting the enrichment of the volatile compounds on the adsorbent trap. Hence, efficient concentration of trace level volatiles | | | | | | | MASTER GC Fast Gas Chromatograph
Increases your analytical productivity, DANI MASTER GC offers a new approach to the world of gas chromatography by dramatically decreasing sample run times in a wide range of GC applications. Faster than a conventional GC, DANI MASTER GC increases analytical productivity with an excellent sensitivity.
The modular design of the components allows to easily change or upgrade any GC configurations.
Up to three injection units and three detectors can be mounted simultaneously.
A complete accessibility of the whole system allows easy maintenance and a real cost reduction.
An intuitive Touch Screen interface controls both the GC and AS with an ultimate simplicity. DANI MASTER GC replaces the complicated keypad user interface with a user friendly, large, full colour Touch screen which avoids a continuous “up and down” among the multiple levels and simplifies the use of the operating manual.
DANI MASTER GC includes a complete range of injectors and in particular DANI PTV ensures unprecedented sample integrity and supports the stringent timing requirements of FAST GC through a rapid cool down.
DANI MASTER GC features a full range of high sensitive detectors. Each detector incorporates a Digital Pressure Control (DPC) for digital setting of the detector gas flowrate.
The detectors data acquisition rate is up to 300 Hz for a better repeatability and accuracy of chromatographic data. | | | | | GC1000 Digital Gas Chromatograph
C1000 is very versatile and easy to use.
DANI GC1000 gas chromatograph is very versatile and easy to use. Even with its extremely reduced dimensions it is fully equipped to satisfy the most demanding user. The flexible and adaptable basic structure can accommodate up to four injectors and detectors for packed and capillary columns.
The system allows to easily move from a minimal to a very complicated configuration with minor changes and at very reduced costs. The oven is extremely spacious and easily accessible and contains many columns allowing for complex analytical configurations.
All parameters can be controlled by a powerful internal microprocessor thereby guaranteeing total accuracy and repeatability of timing and temperatures.
Electronic gas regulation, for both injectors and detectors, allows to include in the method timing, temperatures and all gas flow rates. Just recall the method previously stored to reproduce, from time to time and on different instruments, retention times and sensitivity with the utmost accuracy.
The instrument also provides constant column flow rate operation to improve analysis results, whilst preserving the analytical column.
DANI GC1000 offers a complete range of injectors, all equipped with electronic pressure control, which allow an accurate injection of all samples in packed or capillary columns. DANI not only provides traditional split/splitless and packed column injectors, but also the programmable temperature injector PTV.
| | | | | MASTER AS Liquid Autosampler
MASTER AS improves precision of analysis
Providing innovative sampling solutions, DANI MASTER AS maximizes lab productivity by offering leading edge technology in automation. Merging robotic technology with advanced three-dimensional space movements (X-Y-Z), it provides unprecedented automation and greater flexibility in sample capacity.
DANI MASTER AS provides maximum sample throughput with a standard 160 sample tray for 2 ml vials or optionally a 65 sample tray for 10 ml vials. The same sample can be introduced up to 100 times in a single injector or into three injectors alternatively. The sample can be taken at different selectable needle depths thus performing an extraction directly from the vial.
Parameters are easily programmable to optimise both the most convenient sampling method for extremely volatile or viscous samples and the best injection technique.
These parameters include:
number of solvent or sample washings, plunger speed during sampling and injection, delay time of needle into the injector before and after injection and depth of needle into the injector itself.
MASTER AS includes customized injection to optimise the sampling with different samples and any kind of injection technique.
Even the most skilful operator can no longer compete with an automatic system in terms of precision and accuracy.
| | | | | | | MASTER TD Thermal Desorber
MASTER TD increases sensitivity of your analytical system
Thermal Desorption technique is becoming the alternative method to traditional solvent extraction offering many advantages like a considerable increase in sensitivity (up to 1000-10000 times), a higher percentage recovery (over 95% for all volatile substances), a reduced sample handling and the reuse of the sampling tubes which decreases the costs.
Without the use of solvents, the thermal desorption eliminates the introduction of impurities into the column by masking the peaks of interest. This minimizes the negative effects in the environment, safeguards the operators’ health and eliminates considerable solvents costs.
DANI MASTER TD guarantees excellent analysis performances by using a two-stage thermal desorption process: the volatile and semi-volatile compounds (up to C44) are desorbed from the sample by heating in a flow of inert gas and refocused in a narrow-bore packed trap kept a low temperature and filled with one or more sorbent materials. The trap is heated instantaneously and the components are introduced in a narrow band directly into the analytical column through a heated transfer line.
The electrical cooling device of the trap, able to cool down to –40°C, is included in the MASTER TD.
Used with suitable sorbet material it allows focusing even of extremely volatile compounds.
Cooling is very fast and no cryogenic liquid is required.
A patented instant desorption system preserves resolution and chromatographic accuracy, in particular in applications with capillary columns.
MASTER TD operates automatically from thermal extraction to injection into the analytical column. The synchronization with the gas chromatograph, the 50 places carousel, the high

HSS 86.50 ... reduces sample preparation and assures great precision
DANI HSS 86.50 static headspace sampler is the result of 30 years of experience in the production of automatic samplers offering most accuracy, reliability, outstanding repeatability and increase in the productivity of analysis activities.
It allows volatile compounds to be extracted from a non-volatile matrix and to be quickly introduced into a gas chromatograph with reduced sample preparation.
Whatever the sample type, the process no longer requires difficult extraction, purification and preconcentration which often cause errors.
DANI HSS 86.50 is easy to use and can be coupled to DANI GC or any other gas chromatograph or GC/MS.
DANI HSS 86.50 is able to analyse up to 44 samples in 20 or 10 ml vials and to optimise analysis times for high productivity: one sample is heated while the previous sample is analysed. This process eliminating waiting times between each run.
HSS 86.50, used with the DANI PTV injector, is the ideal solution to obtain maximum sensitivity and best analytical performances with highly volatile compounds at low concentrations.
The headspace sampling technique is a tested method used in the most different fields of application.
DANI HSS 86.50 allows analysis times to be reduced and increases productivity while maintaining high standards of precision in a wide range of applications like quality control of food, drinks and industrial products e.g. for the determination of monomer residues in polymers or residual solvents in food packaging.
