Stable Isotopic Analysis
Q1. Will the samples be ground up in a powder? If not then how fine will the samples be ground?”?
Response: Dried seed samples will be ground with a Perten Instruments
Laboratory Mill 3310 using a Fine Grinding Disc.
Whole plant materials will be ground as follows (taken from a manuscript):
“…ground to pass a 2 mm screen using a Wiley Mill (Thomas Model 4 Wiley® Mill, Thomas Scientific, NJ USA). After mixing, a subsample of about 1/4th of each sample was ground again using a UDY Cyclone sample mill (MODEL 3010-014, UDY Corporation, CO USA). After thorough mixing, a subsample of about 0.2 g was then transferred to a 15 ml tube (part # 2252-PC-30; SPEX CertiPrep, Inc., NJ
USA) and a 9.52 mm diameter stainless ball (440C Stainless Steel Ball, Tolerance/Grade: 100, Abbott Ball Company, Inc., CT USA) was placed inside the tube along with the sample for grinding. Each sample was ground for 9 min at 1,200 rpm using a Geno/Grinder equipped with a large clamp assembly and a 15 ml tube foam holder (SPEX CertiPrep, Inc., NJ USA). Thereafter, about 3 mg of powdered sample was carefully packed in tin capsules and arranged in 96-well plates (Costech
Analytical Technologies Inc., CA USA)…”
