What EIM-PADS stands for?
EIM-PADS is a shortcut for Ethanol Isotope Measurement – Preparation Automatic Distillation System.
The missing link in Isotope Analysis
We have developed, certified, and patented a new isotope method for analysis of wine, grape must, fruit juices, alcoholic beverages, and honey – Ethanol Isotope Measurement – Isotope Ratio Mass Spectrometry (EIM-IRMS®).EIM-IRMS® method is capable of providing unique molecular fingerprint that cannot be reproduced or counterfeited. It is used to determine production practices used in wine and honey production, and product authentication for the purpose of protecting producers and consumers.
EIM-IRMS® is significantly more precise, sample analysis is shorter, and the equipment used, Isotope Ratio Mass Spectrometry (IRMS) is much more readily available and cheaper than equipment for nuclear magnetic resonance (NMR) method, which can only be used for wine with known geographical origin.
Instrument Description
EIM-PADS is totally automated and user-friendly equipment which represents a part of the SG Isotech's EIM-IRMS concept for isotopic analysis of ethanol. As a preparation unit it simplifies the extraction of ethanol analyte from wine, fermented fruit juices, fermented honey or alcoholic beverage samples for easier determination of deuterium isotopes in ethanol.

How many distillation units can be in one battery? If it is possible to make for example 4 or 5 (or less) units in one battery?
EIM-PADS can contain up to 10 distillation units
What kind of product can I distillate on EIM-PADS?
Wine, fermented fruit juices, fermented honey as well as alcoholic beverages can be distilled on the EIM-PADS system.
Is it possible to distillate few samples in one time (or different origin products in one time)?
Of course, it is possible to distill different samples simultaneously, regardless of their origin.
What is the volume of sample for distillation? If it will be the same for different products?
The volume of the sample to be distilled is always the same and is 250 mL.
What is the volume of flask for distillation?
The volume of the distillation flask is 500 mL.
The process of distillation is going automatically or I have to control the temperature by myself?
The whole distillation process is fully automated and software-driven, so the process ends automatically when ethanol is completely pre-distilled and converted to the distillate.
In what temperature the distillation starts and finish? Why?
Distillation begins when the temperature at the top of the distillation unit reaches 78.2 °C and ends when the temperature exceeds the value of 79 °C. The ethanol evaporation temperature is exactly within this range of values and as soon as the temperature exits this range means that there is no more ethanol in the superheated steam and that the distillation process is complete.
How the distillation unit controls the temperature of distillation?
Temperature is controlled by EIM-PADS software.
What has to be the recovery of distillate for instance from sample of wine? Why it has to be like that?
The recovery of the sample must be greater than 90% since in this case, the isotopic fractionation of ethanol during distillation is minimal.
What is the average value of alcoholic strength of sample of wine? How can I check it and why I have to do it time to time (or how often)?
The average alcoholic strength of the distillate is in the range of 92-94% vol. The alcoholic strength of the distillate must be determined for each sample prepared since the quality of the analysis itself depends on it, and the recoverability calculation first.
Could I write the name of samples in the program?
Yes, sample names can be entered into the EIM-PADS program.
How long does it take to distill a sample? Does distillation time depend on the sample?
Yes, the distillation time in the first place depends on the amount of ethanol in the sample. The average distillation process lasts from 1.5 to 2 hours.
Can I stop distillation at any time and what would happen if I took only 5 or 10 ml of distillate, for example?
Distillation may be stopped at any time, but it is not advisable in this case to use distillate for authentication because the process is not complete and is not quantitative by itself. Ethanol must be quantitatively extracted from the sample to be analyzed in order for the results to be reliable and valid.
Does the distillate need to be stored in the refrigerator or can it be kept at room temperature?
Yes, it is advisable to keep ethanol distillate samples in the refrigerator at low temperature to avoid evaporation and hence isotopic fractionation and loss of sample origin information.
Do you have all elements and details in one unit or I have to find some elements in another company?
Yes, all spare parts for EIM-PADS can be purchased directly from our SG ISOTECH Company.
Why this automatic unit is better than usual distillery?
It is not possible to concentrate ethanol by standard distillation to the ethanol concentrations obtained on EIM-PADS.
How much space it could occupy in the lab?
The space occupied by EIM-PADS depends first on the number of distillation units within a single battery. if the distillation battery contains 10 distillation units then the space it occupies is about 8 square meters.
Why Choose EIM-PADS® Module
This is a very promising method in the field of wine and alcoholic beverage production!
