Total Organic Carbon (TOC) analysis is a crucial test in laboratories that assess water quality. In this comparative report, we will break down the technical specifications and features of two titans in the industry: the Kalstein YR04950 and the Elementar Acquray series.
Both analyzers employ wet chemical oxidation by UV for measurement. However, in terms of measurement range, the Elementar Acquray series boasts a superior capacity of 2μg/L to 20,000mg/L, compared to the range of the Kalstein YR04950 from 5μg/L to 10,000mg/L.
Despite this, both devices use NDIR detectors. However, Elementar’s detection limit is lower at 2μg/L, while Kalstein’s is 5μg/L.
Adaptability in Measurement and Dilution
The Kalstein YR04950 measures TC, TIC, TOC, NPOC and requires manual dilution. In contrast, the Elementar Acquray measures TOC, TIC, ROC and can automatically dilute. This feature allows for greater convenience and precision, especially in high-volume tests where automatic dilution can save time and reduce errors. https://kalstein.net/en/product/total-organic-carbon-analyzer-yr04950/
Both the Kalstein and the Elementar are PC controlled. However, Elementar offers a notable advantage with its ability to analyse both liquid and solid samples, provided the necessary modules are added.
In terms of compliance, both devices support 21 CFR PART 11, IQ, OQ, PQ documents.
Advantages and Disadvantages: Which is most suitable for your laboratory?
In summary, the Elementar Acquray offers a wider measurement range, a lower detection limit, and the ability to work with both liquid and solid samples. While these are notable advantages, it also tends to have a higher price.
On the other hand, the Kalstein YR04950, although it has a more limited measurement range and detection limit, is a reputable manufacturer that offers a high-quality product at a more accessible price.
Your final decision will depend on the specific needs of your lab and your budget. Therefore, we suggest you carefully evaluate these characteristics before making your purchase or sale, and remember that price should not be the only factor in choosing your laboratory equipment.
In conclusion, both the Kalstein YR04950 and the Elementar Acquray are highly capable devices that comply with current regulations. The choice between Kalstein and Elementar will depend on your specific needs, always detailing the benefits obtained in exchange for the purchase price.
