Application
Formamidinium iodide (FAI) is a compound that finds significant application in the field of photovoltaics, particularly in the development of perovskite solar cells. Formamidinium-based perovskite materials derived from FAI have also shown potential in other optoelectronic applications. These include light-emitting diodes (LEDs), photodetectors and lasers.
Organohalide based perovskites have emerged as an important class of material for solar cell applications[1][2][3][4]. Our perovskites precursors with extremely low water contents are useful for synthesizing mixed cation or anion perovskites needed for the optimization of the band gap, carrier diffusion length and power conversion efficiency of perovskites based solar cells.

Application
Methylammonium iodide (MAI) has been widely used in the development of perovskite solar cells. MAI is typically used as a precursor material in the fabrication of perovskite thin films. It acts as a source of methylammonium cations (CH3NH3+) and iodide anions (I-) that are necessary for the formation of the perovskite crystal structure.
Methylammonium iodide, an organic halide-based perovskite material, can be used in the fabrication of high-performance organic solar cells.
Organohalide-based perovskites have emerged as an important class of material for solar cell applications. Our perovskite precursors with extremely low water contents are useful for synthesising mixed cation or anion perovskites needed for the optimization of the band gap, carrier diffusion length and power conversion efficiency of perovskite-based solar cells.

Merck
Buffer tablets pH 7.2 – for preparing buffer solution acc. to WEISE for staining of blood smears, are used to prepare buffer solutions according to WEISE and pH-buffered staining solutions. Phosphate buffer solutions are used in hematology, for the dilution of staining solutions and for the rinsing steps in the staining process. The buffer tablets acc. to Weise will produce a buffered solution (pH6.4/pH6.8/pH7.2) that stabilizes the staining result and gives reproducible staining results. Buffer solution acc. to Weise pH 6.4 results in bright-orange stained erythrocytes and differentiated stained cells with nuclei, whereby the erythrocytes are stained orange when using pH 6.8. Buffer solution acc. to Weise pH 7.2 produces grayish stained erythrocytes and intense red-violet stained cells with nuclei.
100 tablets are sufficient for 100 l buffer solution, each produced solution can be stable up to 4 weeks. Buffer tablets acc. to Weise are IVD products and CE registered.

The method corresponds to DIN 38405-13 and is analogous to ISO 6703, EPA 335.2, APHA 4500-CN- E, and ASTM D2036-09 D.
This Spectroquant® Cyanide Reagent Test allows the accurate quantification of the free and readily liberated cyanide content in aqueous samples.
Method applied: Cyanide ions react with a chlorinating agent to form cyanogen chloride. In a follow-up reaction with 1,3-dimethylbarbituric acid in the presence of pyridine a violet dye (König reaction) is formed which is determined photometrically (only free cyanide. For readily liberated cyanide samples must be decomposed by digestion).
The Spectroquant® Reagent Test Kits contain highly stable, ready-to-use reagent mixtures to perform the analysis according to the procedure described in the accompanying instruction leaflet.
All our Cell and Reagent Test Kits are equipped with the unique Live ID which allows seamless method recognition and contains essential information such as lot number, expiry date, and automatic calibration updates.
