SML (specific migration limit) analysis of individual substances for compliance assessment
Quantitative analysis of substances with limits (SML, SML(T), QM, QMA etc.) or non-evaluated substances by gas chromatography (e. g. HS-GC, GC/MS), liquid chromatography (e. g. HPLC/MS), mass spectrometry with inductively coupled plasma (ICP-MS) in food simulants or foodstuffs after migration or (residual) content determination in the material or article.

Overall migration acc. Reg. (EU) No 10/2011 standard test conditions (OM 0 - OM 7)
Regulation (EU) No. 10/2011 (PIM)/DIN EN 1186 classical food simulants for all filling goods (no alternative tests like Isooctane testing): A = Ethanol 10 % (v/v), B = Acetic acid 3 % (w/v), C= Ethanol 20 % (v/v), D1 = Ethanol 50 % (v/v), D2 = Vegetable oil, E = poly(2,6-diphenyl-p-phenylene oxide) (Tenax ®)

Damage analysis/examination of complaints
In many cases, it is not immediately obvious which kind of tests are necessary and reasonable for clarification. Furthermore, test results which are available in short time are often helpful for further decisions. Our “diagnostic concept” provides the agreement of a limited budget (normally 700,- up to 1.000,- Euro) for the screening and evaluation of information already available as well as the realisation and assessment of first tests according to an agreed schedule. The result is a more detailed view of the damage, possible solutions and indications for additional and reasonable investigations and researches are given. You will receive first reliable test results and an appropriate documentation of the current situation at short notice and at a fixed price. Information on the frequency of damage, time of detection, technical information such as material structure or test results already known are helpful for a successful processing as experience has shown. If available, please send us reference samples, data sheets, specifications.

Bond strength/peel force of laminates/multi-layer films/bondings (temperature range - 40 up to + 120 °C)
DIN 53357 A (historical)/ASTM F 904/DIN EN ISO 11339 peel test after separation of the laminated layers (accredited test method). In addition to determining the peel force to delaminate the laminate, we also evaluate and document the delamination characteristics resp. the delamination mechanism (peeling off of the printing ink?Remaining of the adhesive layer? Tearing of the film ? Transfer of ink to the opposite side of the material ? ...)

Infrared (IR) spectroscopy
Identification of materials, contaminations, additives, laquers, adhesives, adhesive-based anti sealing effect etc. with different techniques depending on sample and problem

Opacity measurement
The measurements are carried out using a spectrophotometer according to ISO 2471 or DIN 6125. An opacity card (Leneta) type 2 a serves as a black and white base according to DIN 6125.

Oxygen transmission rate (OTR) of plastic films, laminates, coated papers, Alufoils, etc.
Coulombmetric (oxygen specific) carrier gas method Method (Ametek/ Mocon). Usually deviating from the standard as a double determination
