ETHOS X

Advanced Microwave Extraction System for GC and HPLC Analysis

opzioni binarie stop loss Milestone ETHOS X

her explanation Samples submitted for GC and HPLC analysis require pre-treatment. The fundamental step in sample pretreatment is the extraction of the compounds of interest from the sample matrix. This is the least evolved -many people still use the Soxhlet method invented in 1879-, most error-prone step in the overall analytical procedure.
The use of microwave energy to accelerate solvent extraction procedures was first described by Ganzler et al. in 1984. These researchers used polar, microwave absorbing solvents or mixtures to extract crude fat from food and pesticides from soil matrices. Microwave extraction rates were found to be significantly faster, with recoveries comparable or superior to traditional Soxhlet extraction, and with a substantial reduction of the amount of solvent required.
The new Milestone ETHOS X is an advanced microwave extraction system offering the best technology currently available for GC, GC-MS and HPLC sample preparation.

here are the findings Microwave extraction is completed in just few minutes. The Milestone ETHOS X can simultaneously process multiple samples in a matter of minutes. Microwave assisted extraction uses closed vessels to heat the extraction solvent above its atmospheric boiling point. The elevated temperature increases the solubility of the analytes of interest and lowers the viscosity of the solvent, allowing it to better penetrate the matrix. This leads to dramatically reduced extraction times.

http://bunker.nu/?komyniti=flashback-Sildenafil-Citrate-p%C3%A5-n%C3%A4tet&cf5=5a An important feature of the ETHOS X system is that it easily adapts to existing extraction chemistry. This is accomplished through the use of a unique, patented material, called Weflon. Without Weflon, extractions could only be performed with polar solvents (Acetone, Methanol, etc.) or mixtures of polar and non-polar solvents, because non-polar solvents are not heated by microwaves. Weflon eliminates this problem by acting as a coupling agent. Weflon stir bars are heated by microwaves and they subsequently transfer this heat to the non-polar solvent.

Effective and consistent

you could try these out Microwave extraction produces equal or higher analyte recoveries than older methods. Thanks to a combination of higher extraction temperatures, closed vessels, magnetic stirring, and precisely controllable temperature conditions, users of microwave extraction can expect a better quality of the results. The homogeneity of the microwave field and the precision of the temperature control are key elements in microwave extraction.

http://purposeagency.com.au/?kolka=dating-equation-age Lower solvent usage reduces the costs of solvent purchase and disposal. Microwave extractions are carried out in closed, sealed vessels. The matrix is constantly bathed with hot solvent in a self-promoting reflux action with no loss of volatile analytes or solvent. The use of closed vessels, with the speed and efficiency of microwave heating, allows extractions to be performed with significantly less solvent, without sacrificing accuracy or precision. The simplicity of the microwave technique reduces the attended labor time and increases overall productivity.

Productivity matters

Largest microwave cavity

Largest microwave cavity

my explanation The new Milestone ETHOS X microwave cavity has a volume in excess of 70 liters, by far the largest currently available.
Why is this important and what are the main implications of this design? Firstly, extraction rotors with more sample positions can be accommodated thus improving productivity and sample preparation throughput. Secondly, the microwave unit is inherently much safer, because a larger cavity better contains gases escaping from vessels, should there be a sudden over pressurization.

Highest microwave power

Highest microwave power

http://putnagroznica.com/?prometey=en-ucuz-forex&72d=d5 The ETHOS X is equipped with two 950 Watt magnetrons for a total of 1900 Watt making it the most powerful microwave extraction system available. The system additionally employs a rotating diffuser that evenly distributes the microwaves throughout the cavity. High power coupled with the diffuser enables very fast heating of high throughput rotors.


Temperature and pressure sensors

Temperature and pressure sensors

speedbot trading The new Milestone ETHOS X is equipped with the most advanced yet easy to use reaction sensors for complete quality control of the extraction conditions. Direct temperature and pressure control are used in a single reference vessel. In all vessels, contact-less temperature is used where the actual temperature of each and every vessel is continuously shown on the instrument control terminal during the microwave run, allowing an instant visual check of the extraction conditions.
In addition, a contact-less pressure sensor monitors and controls all vessels simultaneously, preventing any leakage or venting.

Highest safety: Pressure-responsive door

Highest safety: Pressure-responsive door

http://borokohash.com/?firmino=worcester-dating-south-africa&35f=6e The ETHOS X features a full stainless steel door with an innovative opening and self-resealing mechanism.
Should there be a sudden overpressurisation of the cavity, the door slightly opens for rapid and safe pressure release and the microwave power is instantaneously cut off. Immediately afterward, the door is pulled back, resealing the cavity.
For additional safety, an automatic door locking system does not allow the user to open the ETHOS X door during the microwave run. At the end of the run, the door remains locked until the solutions have cooled down to a user preset temperature.

 

User interface

ETHOS X User interface

important site The ETHOS X is controlled via a compact terminal with an easy-to-read, bright, full-color, touchscreen display. The terminal is provided with multiple USB and Ethernet ports for interfacing the instrument to external devices and to the local laboratory network. The terminal runs a completely new user-friendly, icon-driven, multi-language software to provide easy control of the microwave run.
Simply recall a previously stored method or create a new one, press ‘START’ and the system will automatically follow the user defined temperature utilising a sophisticated PID algorithm. Several applications, including all US EPA and ASTM methods available, are preloaded in the ETHOS X terminal. There is no need to input the number of samples or weights being extracted, as the software will automatically regulate the microwave power accordingly. This assures a consistent quality of extraction and simplifies the use of the instrument.
