| Class ID: | 3.23 |
| Class Name: | polyester |
| Polymer: | poly(ε-caprolactone) |
| Matrices: | 9-nitroanthracene (602-60-8) α-cyano 4-hydroxycinnamic acid (28166-41-8) dithranol (1143-38-0) |
| Salt: | NaI, NaTFA, AgTFA |
| Solvent: | tetrahydrofuran |
| Recipe | For all PCL polymers, THF stock solutions of 9-nitroanthracene as the matrix (20 mg mL−1) and NaI as the counterion (10 mg mL−1) were used. The polymer sample was prepared at a 2 mg mL−1 concentration in THF. MALDI samples were prepared by combining 50 μL of polymer solution, 100 μL of counterion solution, and 200 μL of matrix solution. For all PEG polymers, THF stock solutions of alpha-cyano 4-hydroxycinnamic acid (20 mg mL−1) and sodium trifluoroacetate as the counterion (1 mg mL−1) were used. The polymer sample was prepared at a 2 mg mL−1 concentration in THF. MALDI samples were prepared by combining 20 μL of polymer solution, 0.5 μL of counterion solution, and 10 μL of matrix solution. For all PSt polymers, THF stock solutions of dithranol (20 mg mL−1) and silver trifluoroacetate as the counterion (1 mg mL−1) were used. The polymer sample was prepared at a 2 mg mL−1 concentration in THF. MALDI samples were prepared by combining 20 μL of polymer solution, 0.5 μL of counterion solution, and 10 μL of matrix solution. |
