This research was done to compare two different types of method in measuring the total arsenic using hydride generator quartz cell AAS (HG-QFAAS) and inductively coupled plasma mass spectrometry (ICP-MS) measurement. These methods were validated using CRM DORM-2 ([As] =18.0 µg g-1 ±1.
The title salt, K(+)·C(8)H(8)NO(5) (-) [systematic name: potassium (2R,5R,Z)-3-(2-hy-droxy-ethyl-idene)-7-oxo-4-oxa-1-aza-bicyclo-[3.2.0]heptane-2-carb-oxyl-ate], a widely used β-lactam anti-biotic, is usually chemically unstable even in the solid state owing to its tendency to be hydrolysed. In the crystal structure, the potassium cations are arranged… (More)
