--------------------------------------
- I. Sample measurement and analysis -
--------------------------------------
a. Protocols followed and references:

b. Filter type
    1. Filter diameter and nominal pore size: 
    2. Make and type (e.g., Whatman GF/F): 
    3. Any pre-treatment applied to the filters (e.g., Combustion temperature, and duration): 

c. Sampling and processing 
    1. Method of filtration (e.g., bench top, in line system):  
    2. Replicate reporting method (select one): 

    [ ] Option A (Recommended): Individual replicate data provided separately 
    Each replicate must be reported on a separate row in the data matrix 
    Filtration volume (volfilt) must be reported for each replicate 

    [ ] Option B: Averaged data provided 
    Include all of the following with averaged values 
    Number of replicates combined (bincount) 
    Standard error (or standard deviation or %CV) of replicates (e.g., <fieldname>_se) 
    Filtration volume (volfilt) and its standard deviation (e.g., volfilt_sd) 

    3. Were number of replicates per reported sample in the data matrix (i.e., bincount)?  

    4. Was variability reported in the data matrix? E.g., standard error (<fieldname>_se), or standard deviation, or % cv 

d. Post sampling processing
    1. Acidification step: Mode of application (i.e., fumes vs. solution): 
    2. Drying method and temperature (length of time in oven, desiccator, etc): 
    3. Elemental analysis: 

e. Elemental analysis
    1. Instrument make and model: 
    2. Calibration standard: 
    3. Reference material used and performance metric results relative to reference:

f. Blank corrections
    1. DOC/DON adsorption (“filtrate”) blank correction should be measured and applied (Moran et al. 1999). Were samples blank corrected?
