The MASTER AS allows the utilization of up to seven different syringe capacity types ranging from 5 μL to 500 μL, offering a great choice of injection volumes from 0.1 μL to 500 μL. The syringe can be easily exchanged by using the Syringe Replacement function, which brings the Y axis of the MASTER AS to a handy position.
The MASTER AS presents unmatched injection capabilities. The same vial can be sampled up to 100 times and the sample can be introduced into three different injectors without requiring autosampler re-alignment or any calibration procedure.
A Dynamic Approach to High Sensitivity Headspace Analysis
Extending Sensitivity for a deeper characterization of samples
DANI Master DHS Dynamic Headspace Sampler provides you with the most sensitive and versatile system for headspace analysis.
In Dynamic Headspace Sampling technique, samples containing volatile organic compounds are placed in a closed vial and after thermostatting and initial molecules’ partition the headspace is purged by a constant flow-rate of inert gas for a fixed time. Volatiles are swept from the headspace and transferred to an adsorbent trap where they are cryofocused and concentrated. At the end of the concentration step, the trap is rapidly heated, the volatiles are desorbed in back-flush mode and sent to the GC column.
When compared to Static Headspace sampling, Master DHS presents two main advantages:
the extraction step is no longer dependent on the thermodynamic equilibrium between the liquid/solid phase and its headspace. It means that extraction is less affected by the sample matrix. This benefit is particularly evident for compounds that show high solubility in the matrix and consequently low sensitivity when the Static Headspace approach is applied.
Increased sensitivity for all analytes as a larger amount is extracted from the sample, concentrated and injected, compared to the Static Headspace approach where only a fixed volume of gas is sampled from the vial.
Master DHS can be used for both liquid and solid samples. Furthermore, it provides analysis of sample “as is“, without requiring the use of solvents for extraction and concentration purposes. This increases the sensitivity and eliminates any concern about solvent toxicity and solvent disposal problems when compared to a liquid extraction technique.
The Innovative Way for Water Analysis
Delivering Performance in Regulated Environments
DANI Master P&T – Purge&Trap Sampler offers the most reliable, high performing Purge&Trap volatiles extraction technique for ultra-trace VOCs analysis.
With its innovative design, Master P&T eliminates any risk of carryover and significantly improves chromatographic efficiency. Excellent analytical performance is guaranteed by the instant desorption trap that assures the complete transfer of the analytes and their injection into the analytical column in a very narrow band to preserve chromatographic resolution.
In order to maximize purging efficiency and minimize the migration of water to the GC or the GC/MS system, the innovative Dew Stop device efficiently removes water maintaining volatile compounds recovery unaffected.
The use of a precise flow of inert gas through the original and specifically-designed needle enables the volatiles to be swept from the sample and focused in a sorbent packed trap. The instrument configuration and process design allows a smooth extraction without the formation of foam. Analytes are then thermally desorbed and introduced into the gas chromatographic column. The highest recovery of the volatiles and the optimal injection result therefore in an unmatched sensitivity.
Master P&T fully complies with the official norms requirements ensuring at the same time superior analysis performance thanks to the accurate and precise control of the entire sampling process, along with the automatic standard addition, the overlapping incubation time capability, and the absence of cross-contamination.
The intuitive control through the software offers an easily management of all the operating parameters and analytical conditions offering a completely automated solution and allowing the unattended analysis of up to 65 samples with the true fastest cycle time in the industry.

Ultimate Solution for High Sensitivity Detection of Volatiles
The DANI MASTER TD Thermal Desorber offers superior sensitivity, versatility, and productivity for the extraction of volatile and semi-volatile compounds from air and solid matrices.
The excellent analytical performance of the system is guaranteed by the two-stage thermal desorption process and supported by the patented “Instant Desorption” of the trap. This design assures the complete transfer of the analytes and their injection into the analytical column in a narrow band to preserve chromatographic resolution and accuracy.
Solid samples are placed directly into the sampling tubes, while gaseous matrices are sampled into tubes filled with one or more sorbent materials or sampled straightly onto the trap by using the MASTER Air Sampler, which automates the sampling from ambient, gas streams, canisters or sampling bags.
When compared with liquid extraction, the higher recovery of the volatiles and their optimal injection result in unmatched sensitivity. MASTER TD offers an outstanding increase in sensitivity (up to 1,000 to 10,000 times) and a superior desorption efficiency (over 95 % recovery of all volatile compounds). In addition, the technique benefits from the reduced sample manipulation and the cost-effective reutilization of the sampling tubes. The fully automated control of the system provides high sample capacity and optimal sampling tube processing for maximum system productivity.
The intuitive control through the TD Manager software offers a complete automated solution. The easy and flexible management of all operating parameters and analytical conditions permits unattended analysis of up to 50 samples.
The MASTER TD, combined with the MASTER GC, is the solution of choice for air monitoring (indoor, workplace, and ambient air) and for the analysis of soil, polymers, packaging materials, etc.
In addition, the MASTER TD meets and exceeds specifications given in the U.S. EPA (TO-14, TO-15, and TO-17), as well as other international regulations.
Productivity has become of vital importance in most modern laboratories.
The automated and unattended processing of a larger number of samples per day is the real challenge to increase productivity and reduce cost/analysis.
Additionally, Fast GC has resulted in a very effective way to address this challenge providing a significant decrease in the analysis time.
However, when a positive identification is mandatory and mass spectrometric detection is needed, Time of Flight Mass Spectrometry (TOF-MS) is the only technology capable of properly describing very narrow chromatographic peaks due to its fast acquisition rate, independently of the mass range of interest.
DANI Master TOF Plus MS detector performs the fastest acquisition rates (up to 1000 spectra/s) and the widest dynamic range available on the market.
DANI Master TOF Plus is now even more sensitive to match demanding analytical requirement. Approaching the SIM mode sensitivity of common quadrupoles, the new Master TOF Plus is extremely suitable to detect analytes at trace levels, keeping the additional benefits of the full mass spectra information always available.
These capabilities are offered in a truly affordable and extremely compact bench-top instrument.
In combination with the Master GC, the system is the ideal solution for Fast GC and GCxGC analyses to obtain improved productivity and performance.
