Liquid Nutritional Products

The analysis of minerals is of crucial importance for product compliance and quality control.

Liquid nutritional products (LNP) are nutritionally supplemented for patients who are recovering from illness, injury or surgery and for people at risk of malnutrition. In addition to a broad range of vitamins, proteins, lipids and carbohydrates they contain minerals that can be divided in 2 groups:

  • Macro-nutrients Na, Mg, P, K, Ca, Mn, Fe, Cu and Zn (concentration range: mg/100g)
  • Micro-nutrients as fortifiers Cr, Se, Mo and I (concentration range µg/100g).

The analysis of these minerals is of crucial importance for product compliance and quality control. TXRF spectrometer S2 PIOCOFOX allows a rapid multi-element quantification including macro and micro-nutrients in LNP after a simplified sample preparation.
