NEW: Asahipak ODP2 HP

- higher Plate Number (TPN) than ODP-50
- can retain high polarity substances
- good selectivity and retention for alkaline or hydrophile substances
- does not adsorb proteins
- pH 3 - 12

Comparison of the new ODP2 HP-4D with the current RP Phase ODP-50 4

- twice better TPN
- higher retention factor of higher plarity substances and good seperation

New: Polymer Column ODP2 HP-4D

4.6 mm ID x 150 mm
H2O/CH3CN= 55/45
0.6 ml/Min, 40 °C
Polymer Column ODP-50 4

4.6 mm ID x 150 mm
H2O/CH3CN = 35/65
0.6 ml/Min, 40 °C

Sample: 5µl

1. Uracil 30 mg/l
2. Theobromine 75 mg/l
3. Caffeine 130 mg/l
4. Phenol 300 mg/l
5. Methyl benzoate 350 mg/l
6. Toluene 1000 mg/l

ODP2 HP is suited for the analysis of drugs contained in biological fluid

- proteins are not adsorbed
- sharp elution peak
Column Shodex OPD2 HP-2B
Eluent 1 mM CH3COONH4 aq.CH3CN-90/10
Flow Rate 0.2 ml/Min
Detector UV (220 nm)
Column Temp. 30 °C

Comparison ODP2 HP-2B and ODS(A)

The ODS(A) adsorbs the BSA and pressure increased; the performance decreased with increased analysis time

ODP2 HP suitable for LC/MS

- no Ion suppresion, because the ODP2 can seperate drugs from protein
Column Shodex OPD2 HP-2B
Eluent 1 mM CH3COONH4 aq.CH3CN-70/30
Flwo Rate 0.2 ml/Min
Detector UV (220 nm), ESI-MS (SIM)
Column Temp. 30 °C
