Guide and selection support
Infrared digestion systems are used in analytical laboratories for rapid and precise sample preparation, especially for the determination of organic substances such as nitrogen or total organic carbon (TOC). By utilizing infrared technology, they reduce heating and cooling times compared to heating block systems.
Key selection criteria include compatibility with the types of samples to be analyzed, the required temperature range, and integration into existing analytical procedures like Kjeldahl digestion or high-temperature oxidation. Operator convenience and maintenance requirements are also important factors.
LabFinder supports users by providing targeted product information and the ability to compare infrared digestion systems. This helps facilitate the selection of suitable equipment for a wide range of analytical requirements and laboratory processes.
Applications and Benefits
Infrared digestion systems are primarily used in chemical analysis to rapidly and efficiently digest samples. Typical applications include nitrogen determination via the Kjeldahl method and total organic carbon (TOC) determination in water and wastewater analysis. Infrared technology minimizes time requirements due to shorter heating and cooling phases compared to conventional heating block methods. Additionally, these systems are suitable for other high-temperature digestions involving hard-to-oxidize compounds.
Selection Criteria
When choosing an infrared digestion system, several factors must be considered: The type and composition of the samples define the requirements for temperature ranges and digestion methods. Sample volume, sample throughput, and degree of automation are also important. Other key aspects include compatibility with analytical procedures, e.g., Kjeldahl digestion, user-friendliness, and the ability to integrate into the existing laboratory environment.
Variants and Measurement Principles
Infrared digestion systems operate by directly irradiating samples with infrared light, enabling rapid and even temperature development. Variants differ mainly in the number of heating positions, the type of sample vessels used (e.g., tubes, capsules), and the control technology. These devices are specifically optimized to perform fast high-temperature digestions, which is especially relevant for Kjeldahl digestion and TOC determination.
Calibration and Maintenance
Regular maintenance of infrared digestion systems is essential for continuous functionality. This includes checking and, if necessary, replacing heating plates or infrared sources, as well as calibrating temperature control. Proper cleaning of sample holding areas prevents contamination and has a positive impact on measurement accuracy.
Application Limitations
While infrared digestion systems offer fast digestion times, they can reach their limits with certain very complex sample matrices containing extremely resistant compounds. It is also important to ensure optimal separation of processes to avoid interactions between the sample and heating surfaces. The devices are primarily designed for defined digestion procedures rather than general thermal sample treatment.

Frequently asked questions
How does an infrared digestion system work?
An infrared digestion system uses infrared radiation to heat samples quickly and evenly to high temperatures. This decomposes organic components and prepares them for further analysis.
What kinds of samples can be processed with infrared digestion systems?
Typical samples include foodstuffs, animal feed, water, and wastewater. The systems are especially suitable for samples that require rapid nitrogen or TOC determination.
What are important selection criteria for infrared digestion systems?
Key criteria are the required temperature range, number and volume of samples, compatibility with analysis methods, operator convenience, and maintenance effort.
What advantages do infrared digestion systems offer compared to heating block systems?
Infrared digestion systems significantly reduce heating and cooling times, enabling faster analyses with comparable precision.
What limitations exist in using infrared digestion systems?
They are less suitable for extremely robust or unusual sample matrices and are specifically designed for defined digestion protocols. In addition, contact issues between the sample and heating surface can affect results.
