GfL Gesellschaft für Lebensmittel-Forschung mbH
Our Quality Management is based on the norm DIN ISO/EC 17025 and DIN EN ISO 9001:1994. Under these rules resp. their precursors we are accredited since 1992 by DAP (German Accreditation System for Testing). Since 2000 we are furthermore certified by AKS (national accreditation body Hannover) according to the guidelines 93/99/EBG.
The certificates are valid for analysis in the field of "fruit and vegetable juice and related products" as well as "general foods".
For the quality assurance of measurement and testing results quite a few administrative and analytical actions are necessary. These measures as well as all activities in the laboratory that are related to the realisation of examinations are documented in the quality management handbook.
Central aspects are: the quality assurance of measurement results, control of the quality assurance system, preventive actions, customer service and judgement of the management system.
The fundament to achieve correct results is the use of suitable and reviewed methods, therefore it is preferable to use standardised methods. Since official methods are not available for all analyses one has to modify or even develop own methods. These so called "house methods" are then validated according to international standards.
Important criteria therefore are:
The observation of the test equipment in routine operation is then checked through a number of arrangements.
Reference samples are analysed along with every set of sample and results are filled in a control chart specific for each method. From the resulting chart one can easily check if the method performance is stable within the limits set.
Further all laboratory equipment is tested regularly for its functional capability.
Any control data, occurring disturbances, error messages and their trouble shooting are recorded in a operating manual.
Special attention is given to the handling of chemicals, standards and reference materials. This is necessary to assure in the first place that only specified substances are used but also in case of deviation it is essential to have full traceability for cause studies. These controls range from supplier selection over reception inspection of certain batches to total documentation of usage for preparing reagents.
Integral element of further quality assurance is continuous participation in collaborative studies and interlaboratory comparisons. GfL is striving to cover all offered analysis regularly to have revisable proof of the analysis quality.
Results of collaborative studies are examined and stored by the quality assurance.
Apart from the regular controls by the accreditation body at least once year internal audits are performed. This is necessary to routinely check all aspects of the QA system which are:
Results of these internal checks are set out in writing and summed up in an audit report. On the basis of this report the entire QA system is evaluated by the general management and corrective measures are accommodate if necessary.
In addition to the audits mentioned above naturally customers can, under consideration of secrecy, conduct own audits. This possibility has been appreciated a few times already during the last years. We expressly appreciate this development since customer audits are a good basis for a trustful, transparent and last but not least successful collaboration.
Preventive measures are an important element of quality assurance since they markedly reduces sources of error respectively risks in all parts of the laboratory and administration. They are a foundation for longterm quality assurance because they progressively are implemented into the quality management handbook.
In terms of personal responsibility all staff is called upon to continuously identify sources of error and thereby contribute to the continuous improvement process.
Precautionary actions include, a.o.:
In our self-conception as a service enterprise we do not only have highest demands to our analytical results but also to our collaboration with the customer. This begins with consultancy about sensible analysis extends of individual samples as well as reasonable testing plans for a continuous quality control. This includes, where required, specifications about sampling, sample packaging, the number of sample drawings and shipping details.
Also when samples have been received a close communication with the customer is most important for us. In these terms all conspicuities at sample reception or during the analysis are discussed. This way possible continuative action can be initiated even before the ending of all analysis.
Naturally the client is informed in time if possible delays occur. All our reports generated include furthermore a detailed evaluation and interpretation of the findings depending on the analysis extent. Beside legal comments this can also be consumer relevant quality aspects.
After arrangements we additionally allow inspections of our lab, where the customer can watch closely the handling of their samples. If samples delivered are needed for instance for verification reasons we can provide these up to six month after receipt.
Should there, despite of all quality assurance measures, be reasons for complaints our quality management system has rules and procedures how the grievance is dealed with. All complaints, their investigation and if so corrective measures are documented and can be examined by the concerned customer any time.
Yet another considerable element for continuous enhancement and improvement of the system is the periodical review and the aim for new ambition.
Therefore the whole quality management system is evaluated once a year by the general management. For this reason the technical directors point out the current status of the system as well as detected flaws.
The assessment includes at least the following headwords:
