Application

The calcium standard solution may find its following use:

• To determine metals in milk samples using flame atomic absorption spectroscopy (FAAS) and complexometric titration with EDTA
• Estimation of calcium in grape must and base wine by fourier transform near-infrared (FT-NIR) spectroscopy
• In the method development to determine calcium, magnesium, potassium, iron, copper, zinc, manganese and phosphorus in bread samples by microwave plasma-atomic emission spectrometry (MIP-AES)
• Validation of an alternative method to measure calcium and magnesium in biological fluids
• Determination of calcium and zinc in gluconate oral solutions and blood samples by liquid cathode glow discharge-atomic emission spectroscopy (LCGD-AES)[5]
• Development and validation of an inductively coupled plasma-atomic emission spectroscopy (ICP-AES) based method to determine trace elements in vinegar[6]
