Evolution Continues • General: All tested and optimized MULTIWAVE applications can be transferred with minor changes. E.g. Milk Powder 800mg Even buying a new system one can choose from a big pool of tested applications.
Evolution Continues • General: Difficult samples turn out better! More vessels (33%), but: • Multiwave 3000 has 40% more power • X-vessels volume (+100% XF100 / +60% XQ80) Methods from other systems can be transferred easily because the Multiwave 3000 surpass each limit of other instruments. A system with sensors will reduce the efforts for development of new methods to a minimum.
Complete Sample Library • Features: • Only methods for set rotors and sensors visible • Methods available for power and temperature controlled systems • Last four applications in a quick start menu. • Update via Internet or disk possible.
Kinds of Applications Applications available for • For methods running with a p/T sensor • Better comparable results • Needed for US-EPA standard procedures • Solvent extractions mainly temperature controlled • Power profile • Temperature profile • For the use of systems without sensors or p/T sensor. • Available for several samples with exactly defined procedures • Customer specific applications on request against a little fee.
Digestion of Milk Powder • Power profile • Method development • Digestion of the sample with all sensors in power-mode for 4, 8 and 16 vessels • Found method profile should always be 100-150W below the power profile of the measured digestion • Expand digestion time to compensate lower energy input for comparable results.

Total Digestion of Soil • Power profile • Reagents • 5ml HNO3, 1mL HCl • 1ml HNO3, 2mL HF • 12ml Boric Acid 2x 115min 70min
Total Digestion of Soil Task: A big private analytical lab used 3 MULTIWAVE with Rotor 12LF100 to run 3 digestion runs each day 7days a week. Sample throughput: 12 vessels – 2 blanks – 2 references = 4 samples (n=2) 4 samples x 3 runs = 12 Samples/Day/MULTIWAVE 115min – 70min = 45min; 3 runs =135min ( 2 runs more) 3 runs x 57min = 135min Sample throughput: 16 vessels – 2 blanks – 2 references = 6 samples (n=2) 6 samples x 5 runs = 30 Samples/Day/Multiwave 3000
