Sugars and salt determinations are two of the most commonly performed analysis in food laboratories, yet they often give cause of most concern. This is because in many laboratories these determinations are performed using traditional methods such as flame photometers or manual titration using a colourmetric end point.
For salt determination, using a flame photometer required different and un-contained apparatus leading to the emission of gases and exhausts. This in turn requires the need for fume cupboards. When using manual colourmetric end point with either sugars or salts, samples that are coloured or that have artificial colouring added, will often mask or obscure the indicator making it difficult to find the exact end point which results in unreliable data.
With the TitroLine-Easy (TL-Easy) automatic titrator, from Gerhardt UK, these problems can be eliminated. It is an accurate, self-contained programmable titration unit which is suitable for pH and redox titrations. It has its own magnetic stirrer powered from the mains unit's hot shoe. It has 10 pre-selectable programs, five for both pH and redox and is controlled by five multi-function buttons.
