AutoBlock® Fill:

 Operation and Instruction Manual   

 

 

EPA Method 200.8

4.3  Reduce the volume of the sample aliquot to about 10mL at this 

temperature. This should take about 2.5 hours.  

4.4  Place a ribbed watch glass (SC505) over the digestion vessel to reduce 

additional evaporation.

 

Note: When using a watch glass, adjust the set point temperature of the HotBlock so 
that a 50mL, 5% acid solution is heated to 85°C BEFORE placing the watch glass over the 
sample. Laboratory tests have proven  that the addition of the ribbed watch glass will add 
approximately 10°C to the sample temperature, bringing the sample temperature up to 95°C. 

4.5  Gently reflux the sample for 30 minutes.
4.6  Using the polycarbonate transfer racks, remove samples from the HotBlock 

and allow them to cool.

4.7  Add reagent water to bring the sample to the 50mL mark on the digestion 

vessel. Cap and mix.

4.8  If necessary, filter with SC0401 (or appropriate FilterMate® or FlipMate®)   

to remove insoluble material. 

 

Note: The filtration step should be performed slowly with little pressure placed on the 
plunger. If excessive back pressure occurs, stop filtration and allow sediments to “settle out.” 
Applying pressure to the plunger may cause sample “blow through” allowing sediment to 
pass through the filter into the digestate.

4.9  Prior to analysis, adjust the chloride concentration by pipetting 20mL of 

the prepared solution into another 50mL digestion vessel and bring up to 
50mL volume with reagent water. If the dissolved solids in this solution 
are >0.2%, additional dilution may be necessary to prevent clogging of the 
extraction and/or skimmer cones. Note the dilution factor for concentration 
calculations. If the direct addition procedure is being used, add internal 
standards, cap and mix.

5.0  Procedure, Solid Sample Preparation

5.1  For each digestion procedure, transfer 0.5g ± 0.01g of a dried sieved 

sample into the 50mL polypropylene vessel.

5.2   Add 2.0mL (1:1) HNO

3

 and 5mL (1:4) HCl and swirl. Cover the vessel with  

a disposable watch glass (Item # SC505) and reflux an additional  
30 minutes at a sample temperature of 85°C.

  

Note: When using a watch glass, adjust the set point temperature of the HotBlock so 
that a 50mL, 5% acid solution is heated to 85°C BEFORE placing the watch glass over the 
sample. Laboratory tests have proven  that the addition of the ribbed watch glass will add 
approximately 10°C to the sample temperature, bringing the sample temperature up to 95°C. 

5.3  Allow to cool and bring to 50mL volume with DI water. 
5.4  Filter with SC0401 (or appropriate FilterMate) to remove insoluble material.

All QC samples, concentration limitations, elemental lists and reagent specifications 
are addressed in depth in EPA Method 200.8. Safety concerns are also part of the full 
method. Follow the instructions listed in EPA Method 200.8. These steps should only 
be used as a guide to help improve the performance of your HotBlock.
