0 Answers Dear CEM,

I have a question about digestion oven MARS 5. We have an equipment MARS 5 in our laboratory. We need determine proteins in wheat flour and the first step in this method is an acid digestion according to procedure below:

"-Weigh approximately 1,0g or 0,25g of the sample into the test tube and make

- For weighing 1 g add approximately 7 g or for weighing 0.25g add approximately 1.0g of the prepared catalyst (catalyst = 10:1 sodium sulfate : copper sulfate) into the tube with the sample;

- For weighing 1g add 13 ml sulfuric acid or weigh 0.25g add 6.00 mL of P.A. sulfuric acid;

- Place the tubes in the rack, take to the heat exchanger block approximately 400 ° C until complete sample digestion (staining of the sample at the end of digestion is light green);

- After digestion, remove the tubes from the digester block and wait for the sample cool down;

- Turn on the"

My question is if I can replace the digester block of this method by MARS 5. Could we use MARS 5 to this digestion step of the method?

Thank you.

0 Answers Hello, my name is Wellington. I have a problem with the CG 3900. The problem started when the computer battery ran low and we had to change it. From there the problem began when you click on the Galaxie Workstation icon and an error occurs:"Server connection: Unable to connect: EnxPooledTransportException during logon procedure at 142E830: NexusDB: : Cannot locate or connect to network server. [$2C0E/11278]". Could someone help me please? Thanks. Note: All cables are connected.
