You have a complex mixture, an HPLC-method has to be developed immediately? The method should have short run time, should be robust and economical in development and routine work. You expect weeks and even months to work for this task. Resources were used so that other projects must wait and valuable time is wasted. For those who know such situations we have a solution: You give us the compounds. We will inspect the selectivity of your chromatography system and develop a state of the art method with DryLab. Our offer:

-	all necessary experiments
-	peak tracking
-	input of experimental results into DryLab
-	development of a model for your mixture with a buffer (Eluent A) against Acetonitril or Methanol (Eluent B)
-	a. Gradient vs. Temperature model (4 reproducible input runs with a factor 3 in steepness- and 30°C difference in temp.) or
	d. Isocratic: %B vs. Temperature model (4 reproducible input runs: 20%B- and 30°C difference)
	c. Gradient vs. pH-value model (6 reproducible input runs: 3 pH-values with a difference of 0.5 pH-units each at two gradient times) or
	d. Isocratic: %B vs. pH model (6 reproducible input runs: with 20% difference in B, and 3 pH-values with 0.5 units difference) or
-	prove of robustness
-	method development report

For the above mentioned service we offer a price per model of:

If you want to perform the input runs by yourself, the price per model will be:

The prices are without VAT and materials (Eluents, column)
