Adopting the Zeeman method for atomic absorption spectrophotometers usable for ultra-trace element analysis of reagents.
The "AA240Z/280Z" is a device that employs Agilent's unique alternating Zeeman method for background correction, further enhancing the accuracy of background correction for high matrix samples. The temperature control of the graphite tube utilizes a unique dynamic feedback control method to improve reproducibility. Additionally, the use of a CCD camera that monitors the sample injection state allows for further improvement in analytical accuracy. 【Features】 ■ Designed with consideration for running costs ■ Reduces Ar gas consumption by 40% compared to conventional devices ■ The lifespan of the graphite tube is more than doubled ■ Unique temperature control allows for drying temperature to be set in 1°C steps ■ Standard measurement conditions for each element are stored, enabling the creation of measurement conditions for each sample *For more details, please refer to the PDF document or feel free to contact us.
