Acid Evaporator battle Result in Korean Food lab ? 
 
1.   Customer :DS Foods Corporation, R&D
Center 
2.   Analytical Instrument : PerkinElmer ICP-OES
OPTIMA 8300DV

[Test Result of
Acid Evaporator] 
 
1) Recovery Test for Cd
 
 
* Certified Value:
1.6 ppm [Cd] 
* Sample: Rice
flour(Certified Reference Material) 
 
 2) Analysis Progress 
- Target Sample
Volume : 18~20 ㎖ of MDS Digested sample was evaporated to less than 1 ㎖. 
- Setting Temp. :
180℃ 
- Time : Reach to
set value : 40~60 min 
           Evaporation : 60 min 
           Total Time : 2 hrs 
 
à Notes : Microwave Digested samples amount of 8 ~ 9 ml
and additional DI Water amount for washing the outer wall of the MDS vessel
combined became C. 18 to 20 ml of total evaporation fluid. 
 
à Evaluation : The temperature controller is attached
to the main body of the machine, making it easy to use. 
 
Additional Comment
: The recovery acceptable range is 95 to 110 %.  Most of them are within the acceptable range and are satisfactory. 
 
“Compared to a
competitor’s equipment, it is easier to use and integrated design saves space.”
