In cooperation with Milestone Srl, Proanalytica organized a Workshop called Microwave-Assisted Solvent Extraction in its demo laboratory, where the Ethos X device was presented. This interactive seminar lasting 3 days was attended by numerous collaborators from laboratories all over Serbia. Thanks to the representative of Milestone Srl and application specialist, presentations were held on “Fat determination in food samples” and “Extraction of organic pollutants from environmental samples“. In real time, the principle of the device is presented, as well as the extraction process itself. We are proud of the great turnout and thank everyone who attended. You can still schedule your appointment at email@example.com.
We present to you our new newsletter called “Short and clear”!
In this issue, we announce the start of our showroom activities at Autoput za Zagreb, no. 22. The space represents the real working environment of the laboratory and offers equipment and materials that are part of our regular offer. High-quality laboratory furniture materials, the production of which we have been successfully maintaining for more than two decades, are an integral part of our setup, as well as the instrumentation of renowned manufacturers of which we are representatives.
On this occasion, we offer the opportunity to demonstrate the operation of the microwave extraction/hydrolysis and esterification system by Milestone srl, Italy. Schedule your appointment, and our team of engineers and analysts will present the performance of the equipment we offer, give a presentation that will walk you through all the essential aspects of the method in question and answer all your questions. Get informed regularly through our newsletters and contact us to define a visit date for demo work in our space.

Marzipan and drinking cocoa!
One thing can not be missed at Christmas time: Treats, such as marzipan or a hot chocolate! At this time of year, hardly anyone can resist these sweets. But as delicious as it tastes – it can be dangerous. Because the two end products are processed from almonds and cocoa beans, which are mainly imported from third countries. A long and wrong storage makes them more susceptible to molds that produce highly toxic, aflatoxins and ochratoxin A. In order to be able to control excessive toxin contamination, especially during importation, the European Commission‘s implementing regulation has set limits for these mycotoxins that may not be exceeded.
17 mycotoxins at once – CrossTOX® makes it possible
LCTech‘s CrossTOX® columns enable highly efficient sample purification of regulated and expected mycotoxins. At the same time, they improve the conventional dilute-and-shoot application by a QuEChERS-based non-dispersive (SPE) purification procedure.
A specially designed sorbent guarantees a high removal of analytically interfering sustances even from difficult matrices. CrossTOX® can be used to purify both cereal-based matrices as well as nuts, dried fruits and spices can be processed with excellent purification of contaminants with very good results. The loading capacity is 3 mL (corresponds to 0.6 g matrix).
Purification via CrossTOX® is either manual or automated possible with a FREESTYLE SPE roboticsystem or even fully automated in combination with an HPLC Direct Injection module. Depending on the matrix, the majority of analytes are measured without internal standards and with excellent chromatographical results and recoveries. Internal standards and increasing sample purity, also decreases the enormous costs per sample as well as maintenance costs and chromatography times (LC-MS/MS).
Extract 20 g of matrix with 100 mL (84/16 (v/v)) Acetonitrile/Water. After stirring for 30 min, centrifuge the crude extract at 3000 x g and transfer up to 3 mL of the supernatant through the CrossTOX® column into a sample vial using a syringe. An aliquot is analyzed for the mycotoxins aflatoxin B/G and ochratoxin A by LC-MS/MS.
In this way, many samples can be quickly prepared for LC-MS/MS analysis by means of SPE without toxins remaining in the filter material or interfering substances from the matrix, such as fats and carbohydrates, colorants and aromas, negatively influencing the analysis.
The CrossTOX® column not only impresses with good recovery rates, but also shows its strength in reliable quantification without using internal standards, thus enabling immense cost savings per sample. Further advantages are no contamination of injector, cone sweep or transfer tube. This processing protocol allows high sample throughput, significantly extended maintenance intervals and cost reduction. The results obtained show an equally good performance as the immunoaffinity columns (see table above).
Recently we’ve held a new webinar dedicated to advanced microwave extraction for food and feed products.
Our target was to introduce a unique technique for microwave extraction, hydrolysis, concentration (evaporation) and esterification that changes everything we are used to until now. Instead of spending a lot of hours for each process step necessary to reach final result by using a lot of instrumentation, now you are able to make everything done by only one instrument unit in just a few hours.
Milestone Ethos X microwave extraction system offers possibility to run two process step simultaneously (hydrolysis, extraction) in single vessel after which it is possible to concentrate samples in the same instrument by changing only rotor body. Complete process is automated and dictated by single method implemented in software database which enables operator to easily perform extraction process and automatically calculate final result.
EasyTemp technology gives an significant advantage in process reliability among all available techniques:
contactless IR temperature monitoring in each vessel makes an unique advantage that redefine cycle conditions regarding the current readings – method’s temperature profile is adopted every few seconds after the reading at each position is made. By this feature system ensure maximum safety even relatively different matrices are applied to be processed at the same run.
Flexibility: Milestone Ethos X microwave extraction system gives a possibility to run digestion programs beside extraction process using rotor with the same number of vessels – 15 at the same time.
