Sweetener Analysis (Part 3 of 3)
To do: The first attempts with CHROMABOND® HR-XAW show that enrichment by ionic interaction works much better for Acesulfame than for cyclamate, than the hydrophobic interaction using CHROMABOND® HR-X. The results of these experiments will be summarized in an application note and will be published soon. Subsequent analysis with HPLC-MS/MS

Sweetener Analysis (Part 2 of 3)
Figure 3: Influence of the particle size Conditions: SPE Column type: CHROMABOND® HR-X polypropylene columns 45 µm or 85 µm, 3 mL, 60 mg; Sample pretreatment: addition of 0.25 mL 1 mol/L KH2PO4 buffer pH 2.5 to 10 mL water sample solution; Conditioning: 3 mL methanol, 3 mL KH2PO4 buffer (25 mmol/L pH

Sweetener Analysis (Part 1 of 3)
Determination of residues of sweeteners in fresh water In water analysis the investigation of residues of sweeteners has gained more importance in the last few years. With the increased consumption of reduced calorie products, many sweeteners are widely distributed in the environment unchanged (without degradation). This is also true for
