Sample volume: 50 ml

The research report is issued in the English language.

Methanol is an organic chemical compound, the simplest one within the alcohol group, occurring as a colourless, volatile and flammable liquid. It is well soluble in water. Based on appearance, smell and, to a large extent, taste, methanol is indistinguishable from ethyl alcohol. Methanol poisoning can be unexpected, which is why it is useful to know the methanol content of the distillate.

This method is intended for colourless distillates only. The assay consists in oxidation of the methyl alcohol contained in the sample under analysis to formaldehyde and subsequent reaction thereof with Schiff's reagent to produce a colour, the intensity of which corresponds to the concentration of methanol, determined using a spectrophotometer, within the concentration range of 0.03-1.00 g/100 mL of spirits at 100 % vol.

Provision of samples:

The test samples can be delivered in person to the company’s showroom in Łódź (it is possible then to choose the parameters tested and make payment on the spot) or sent by mail / courier service to the address 93-373 Łódź, ul. Pryncypalna 125, with a note saying ‘LABORATORIUM’. Additionally, please include with the package the description of samples and analyses selected (confirmation of order and payment via the Browin online store). Samples sent by mail/courier should be put into a clean, neutral container (e.g., after pure mineral water) and well secured in order to reach the laboratory safely.

Completion time:

The service delivery time is related to the number of ordered analyzes and the current laboratory occupancy and is up to 7 days. The analysis is only performed on Tuesdays and Thursdays.

We issue VAT invoices.

Please note: The samples sent are stored for 2 weeks and then disposed of. Any presumptive doubts need to be reported within that period.

CAUTION!

Every country has its own legal regulations governing the manufacturing of ethyl alcohol, wine products, and spirits, introducing them onto the market, and regarding sanctions for non-compliance.
