Who Produces Eureka Kits
What you are about to read is a quick representation of Eureka Lab Division and what it did to succeed in researching, developing and producing
the World ‘s Largest Range of Diagnostic Kits
for chromatographic analytical instruments
Many years ago, Dr. Gilberto Coppa and Dr. Stefano Sartori decided to pursue a professional path that few companies had dealt with:
the analytical procedures existing in clinical laboratories, thanks to the realization of
using HPLC, GC, GC-MS, LC-MS / MS chromatographic techniques.
From the very outset, they concentrated their activity on the development of an Analytical Method for the Determination of Urinary and Plasma Catecholamines in HPLC with Fluorimetric Revelation.
The decision to work with Catecholamine was due to the shared thought, along with many Oncologists, that the need of Formulating a Correct Diagnosis of cancer patients was fundamental and extremely important
pheochromocytoma
paraganglioma
neuroblastoma
The concentration of catecholamines (Noradrenaline, Adrenaline, Dopamine), which are a group of hormones produced by the adrenal gland, are greatly increased in biological fluids in the presence of such pathologies.
To help doctors to properly diagnose these tumor forms, they asked some laboratories about their problems and issues in their structures since the 1970s.
Here are some of the problems raised:
Direct measurement in amperometry was sufficiently sensitive for the analysis of noradrenaline and urinary dopamine, but it was not sufficiently sensitive for the quantitative analysis of urinary adrenaline.
Direct measurement in amperometry was not sufficiently sensitive for the analysis of plasma catecholamines even when starting from a high plasma volume (at least 2 ml).
Direct measurement in amperometry had taken the role of reference technique for a long time, but the amperometric detector proved to be difficult to handle for routine analysis.
Despite the replacement of the amperometer detector with the, more sensitive Coulometric detector, it was still difficult to handle for routine analysis as well as being particularly costly.
After collecting this information relative to the problems arising from the use of the amperometer and coulometric detector they decided to “create”
Our team worked long for the development of a fluorimetric, chromatographic, analytical method for the determination of catecholamines with the benefit that:
International research from the ’90s was geared towards selecting more powerful analytical methods capable of selectively analyzing catecholamines in biological fluids, compared to methods born at the end of the 1970’s in ammeters.
Works published by the Japanese groups of Y. Ohkura, K. Imai, H. Iizuka, M. Yamaguchi and by the Dutch G. Alberts and F. Boomsma, led to the selection of a selective quantitative yield reagent for the catecholic group that was transformed to a benzotriazole group, with a FLUORESCENCE response of 50 times higher than the amperometric detection.
Their work involved the development of a biologic matrix purification method that was more self-explanatory than the methods used up to that time.
After purification, the sample undergoes a process of derivatization.
At this point, the derivatized sample is read in fluorimetry, allowing it to obtain excellent sensitivity and specificity for the analysis.
This has allowed us to reach the much anticipated goal:
the analytical procedures existing in clinical laboratories regarding the dosage of both urine and plasma catecholamines.
But this was just the beginning … Since 2000 the Eureka Lab Division Team, has continued to develop
Initially the Team dealt with
Liquid Chromatography (HPLC / UHPLC) coupled to
detectors:
UV/VIS
FLUORIMETER
(for analysis of SPECIAL CLINICAL CHEMISTRY, CLINICAL PHARMACOLOGY and OCCUPATIONAL TOSSICOLOGY)
We then dedicated ourselves to
Gas Chromatography (GC) coupled to detectors:
FID (flame ionization detector)
ECD (electron capture detector)
MASS SPECTROMETER
(for analysis of SPECIAL CLINICAL CHEMISTRY, OCCUPATIONAL TOXICOLOGY AND FORENSIC TOXICOLOGY)
Finally, since 2008, we have focused our work on
Liquid Chromatography (LC) coupled with
Mass Spectrometer / Triple Quadruple
(for analysis of SPECIAL CLINICAL CHEMISTRY, CLINICAL PHARMACOLOGY AND FORENSIC TOXICOLOGY)
The activity in this report was carried out at the Forensic Toxicology Chemistry Laboratory of the Institute of Medical Sciences of the University of Macerata.The subject of this scientific activity was the comparison of two different extractive procedures for SPE.
In particular, the methods used in analytical activity were compared with those developed by Eureka-Lab Division.
Techniques for urinary opiate and cannabinoid analysis (Delta 9 THC COOH) were evaluated.
The first phase of the activity concerned the comparison of the two methods using calibrators of the two known concentrations, supplied by Eureka.
Subsequently, the comparison covered urinary samples at the Forensic Toxic Chemistry Laboratory, selected on the basis of the positivity for the above mentioned substances.
The sample was divided into two equal volumes.
An aliquot was extracted with the lab method, while the other was subjected to extraction using the Eureka kit supplied and according to the procedures of the company.
The extracts were then analyzed by gas-chromatography-mass spectrometry (GCIMS). The results of the partial procedure can be summarized in:
1) The methods developed by Eureka are not very expensive in terms of time and are practical for the use of ready solutions.
2) Compared to the methods used in the laboratory, the methods produce very clean extracts that have improved the quantizational response of the GC / MS analytics.
Ultimately, the proposed, quick and practical procedures have a particular efficacy in the purification phase of the extracts.

In order to be able to continuously increase the production of new Eureka Kits, the company has for several years been working with the
“STUDY GROUP OF EXTERNAL AUTHORS”
They are Specialists in Clinical Biochemistry, Pharmaco – Toxicology and expert in
Chromatographic Analytical Techniques.
They collect the requests of Doctors who are in close contact with patients and iniziate for the development of Chromatographic Analytical Methods that will then be engineered into EUREKA KITS.
It’s like having many research and development teams across Italy working to increase the development of new chromatographic analytical methods that will then be engineered in the form of ready-to-use kits.
I have always liked the challenges that require method, perseverance and a pinch of genius: Fortunately, my work offers me continually.Since my first years of professional life in university research laboratories I have been involved in the development of HPLC methods under very often “extreme” conditions for the quantity and nature of the analyte or sample to be examined.
Meeting with the brave staff of Eureka Lab Division was a challenge for me: we had to look for ways to combine the research experience with the need for standardization and simplification of the indispensable processes for the diagnostic kits.
It was necessary to bring out some important methods of analysis from the “home made” of the research and bring them into the “reliability” of clinical practice.
This is difficult but not impossible if you can rely not only on technical support, but also and above all on the advice of a group of experienced, enthusiastic and … really good friends.
One of the results of this collaboration was the development and validation of an HPLC method for the determination of plasma tyrosine by fluorescence derivatization, but other similar projects are now in the process of arrival.
The vast field of Oxidative Stress Markers, which I currently deal with, is in fact a further discovery of discovery.

They are also passionate about chromatographic analytical techniques and make available their analytical systems and their human biological samples.
It is crucial to have the opportunity to use more chromatographic analytical systems and human biological samples , because ONLY THEN is it possible to determine
THE KIT’S STRENGTH

“I have performed the external validation of the new Eureka Kit for Plasma Metformin Determination in HPLC.The kit is simple and fast. In just over 1 hour you can get the first results of an analytical session.
Sensitivity and reproducibility are suitable for the monitoring of both in-patient and in-drug patients.
It is especially suitable for diabetic patients with moderate renal insufficiency and for controlling inadequate subjects over time. “
