Microplastics Analysis
Detection | Identification | Quantification
We offer microplastic analyses precisely tailored to the requirements of your samples and projects. Using infrared microscopy (FTIR imaging), we can accurately detect, identify, and quantify particles as small as 10 µm. We account for the unique characteristics of each matrix to provide you with reliable and scientifically relevant results.
Our analyses deliver detailed information on polymer type, particle size, and particle count, forming a solid basis for a wide range of decisions, particularly in anticipation of future regulatory measures.
With our academic foundation, we ensure the highest standards in laboratory practices. Rigorous quality assurance and control measures (QA/QC), along with innovative technologies, guarantee the reproducibility and reliability of your results. Rely on our expertise to advance your projects with precise analyses and comprehensive solutions.
What information do you receive?
Qualitative identity of particles
Here, you receive detailed information on particle identity, particle size, particle size distribution, and the number of particles per identified polymer type.
Quantitative assesment
Here, you receive the exact count of identified polymer particles, along with a statistical evaluation of multiple polymer types if different types of plastics are identified.
Size distribution
The size of plastic particles has a significant impact on their biological uptake by organisms. Here, you will receive a detailed breakdown of the identified particles into different size classes.
Validation and Standardization
| Recovery | Quality control | QC
Validation and standardization are essential aspects of microplastic analysis to ensure the accuracy and comparability of results. Validation methods assess analyses for their reliability, accuracy, and reproducibility, while standardization establishes uniform procedures across different laboratories. These processes are crucial for generating reliable data that comply with international standards. However, the challenge lies in developing consistent methods and standards given the diversity of analytical techniques and procedures.
We have developed a method that enables the validation of spectroscopic imaging analysis, providing meaningful and reliable results regardless of the sample in question.
Contaminations
| Recovery | Quality Control | QC
The issue of contamination during microplastic analysis is significant and can compromise the accuracy of results. Even small traces of plastics from laboratory equipment, the environment, or during sample preparation can skew the findings. To minimize these challenges, analyses require the utmost care and the use of contamination-free materials and equipment. Additionally, strict protocols for sample collection and preparation are essential to eliminate external influences.
At our facility, contamination is accounted for through "blank" measurements integrated into the analyses. Furthermore, only equipment and containers made from plastic-free materials are used, and water and solvents are filtered prior to analysis. Sample preparation is carried out in dedicated flow hoods, effectively preventing contamination from airborne particles.
Sample types
Each sample requires individualized procedures for microplastic analysis. Adjusting the methodology to different sample types such as cosmetics, cleaning agents, fertilizers, beverages, and food, as well as environmental samples, is essential. Through tailored development and validation for each sample type, we ensure that the methodology meets the requirements and characteristics of the respective sample. This approach allows for accurate and reliable analyses, regardless of the sample at hand.
Microplastics Analysis
Step 1: Get into contact with us
In the first step, we discuss your specific requirements together. We determine the type of sample, how the sampling process should be carried out, and which analyses are most suitable for your inquiry. No microplastic analysis is the same – different sample preparation methods are required depending on the matrix. We tailor our approach to the unique characteristics of your matrix to develop the most effective method. We present the available techniques and create a customized plan perfectly suited to your needs.
Step 2: Sample Shipment
In the second step, you send us your sample. We provide detailed guidance in advance on the optimal packaging and shipping methods to ensure the integrity of the sample. Upon receipt, the sample is carefully prepared for analysis, with meticulous attention to avoiding contamination and ensuring the quality of the results.
Step 3: Analysis
In the third step, your sample is analyzed, including quality control measurements. The matrix is first processed to allow the microplastic particles to be transferred onto a filter. The particles are then detected and identified using high-resolution FTIR imaging. This precise and meticulous process ensures reliable results and the highest analytical standards.
Step 4: Data and Report
In the fourth step, we prepare a detailed analysis report that summarizes all results clearly and precisely. This report includes information on polymer types, particle sizes, counts, and other relevant parameters. We then discuss the results with you, address your questions, and assist in interpreting the data, ensuring you can make the most of the analysis results for your purposes.
EU-Regulation Microplastics
On September 27, 2023, the European Union published a continent-wide ban on synthetic polymer microparticles (primary microplastics). This applies to synthetically produced, solid, water-insoluble, and biologically non-degradable plastic particles smaller than 5 mm. Regulation 2023/2055 aims to limit the use of synthetic polymer microparticles in various products to reduce their environmental impact. Transition periods have been granted depending on the industry sector and application. Some polymer types are exempt, such as water-soluble, inorganic, or biodegradable plastics. Annex XVII of the regulation defines testing procedures to verify the respective properties. These testing procedures are also carried out by us when needed.
