Oil and Grease Standards
Oil and Grease Standards
Standards for use with Separatory Funnels
(LLE) or Solid Phase Extraction (SPE)
Delta Scientific offers standards which meet all EPA requirements for
Hexadecane/Stearic Acid Spiking Solution as specified by EPA Method
1664 for quality control sample analysis (see paragraph 7.10 of the
method). Use these convenient, easy-to-use standards with Separatory
Funnels (LLE) or Solid Phase Extraction (SPE) for oil and grease analysis.
Standards are checked gravimetrically and by GC. Oil and grease
standards require refrigeration.
Convenient Snip & Pour Teflon Tubes
Pre-measured standards are packaged in convenient Snip & Pour Teflon
tubes. Just snip the top of the Teflon tube and pour the contents into the
sample container or extraction apparatus. The precise volume of HEM
is delivered to the LCS or Matrix Spike sample.
HEM contents do not adhere to the sides of
the single-use Teflon tube. Inexpensive Snip
& Pour tubes eliminate pipettes and require
no warming prior to use. Each G3025 tube
contains 40mg of extractable HEM per 10mL
aliquot while each G3026 tube contains 10mg
Standards in 30mL Bottles
Standards (G3020) also come packaged in
nine 30mL screw-top bottles. Bottling allows
non-standard volumes to be pipetted. 10mL
of solution delivers 40mg HEM. Standards
are suitable for LCS and Matrix Spike samples
and meet all EPA 1664 requirements for both
Separatory Funnel (LLE) and Solid Phase
Extraction (SPE) techniques.
Certificate of Analysis
Oil and Grease Standards are prepared using
Class A volumetric glassware, analytical balance (0.0001mg) verified against NIST
traceable weights prior to use, and high purity Acetone (<1mg/L residue). All
standards are supplied with a Certificate of Analysis. Stearic acid and hexadecane
purities, CAS # and gravimetric concentration are stated on each certificate of
analysis. Certificates provide lot numbers and expiration dates for each standard.
Each lot of standards is analyzed according to EPA Method 1664 and the results
are provided on the Certificate of Analysis. MSDS is also supplied with each box of
To use, cut off one end of the
Teflon tube and pour solution
directly into the acidified acid or
blank. It is not necessary to rinse
the tube. One hundred percent
recovery of each tube is 40mg.
