The required flow rate of 0.35 mL/min is within the pump range, and the stated pressure range of 300–520 bar is below both the column rating of 600 bar and the instrument limit of 800 bar. The 45 °C column temperature is within the oven range, gradient elution is supported, and the 2 µL injection is within the autosamp... | No adjustment is required. Confirm that the assembled system remains below the column pressure rating during the run. | Reversed-phase UHPLC method using a 2.1 × 100 mm, 1.7 µm column. The flow rate is 0.35 mL/min, the column temperature is 45 °C, and the mobile phase runs from aqueous buffer at pH 3.0 to acetonitrile in a gradient. System pressure is expected to remain between 300 and 520 bar. The column pressure rating is 600 bar. | The sample is soluble in the initial mobile phase. Prepare it in that solvent, filter through a 0.2 µm membrane, and inject 2 µL. | Fully compatible | Can this method and sample be run on the stated instrument without changing the method or instrument configuration? | The instrument supports gradient elution and has a pump flow range of 0.01–2.00 mL/min with a maximum pressure of 800 bar. Its column oven operates from 5 to 80 °C, and the autosampler supports injection volumes from 0.1 to 20 µL. |
The specified 1.20 mL/min flow exceeds the pump's maximum of 1.00 mL/min, so the instrument cannot deliver the method flow rate. The stated 320 bar method pressure is below the instrument and column limits, while the 35 °C temperature and 10 µL injection are within their respective ranges. Those matching parameters do ... | Use a pump rated for at least 1.20 mL/min, or develop and validate a revised method at or below 1.00 mL/min. If the flow is changed, reassess pressure and confirm chromatographic performance; the supplied information does not establish the pressure or separation at a revised flow rate. | Isocratic HPLC method on a 250 × 4.6 mm, 5 µm column. The specified flow rate is 1.20 mL/min, the column temperature is 35 °C, and the mobile phase is a water–methanol mixture. The method specification gives an expected system pressure of 320 bar at the specified flow rate; the column pressure rating is 400 bar. | The sample is dissolved in the mobile phase, filtered through a 0.45 µm membrane, and injected at 10 µL. No special temperature control is required for the sample. | Incompatible as written | Can the method be run as written on this instrument, considering its flow and pressure limits? | The instrument supports isocratic operation and has a pump flow range of 0.05–1.00 mL/min with a maximum pressure of 400 bar. The column oven operates from 10 to 70 °C, and the autosampler accepts injection volumes from 1 to 100 µL. |
The column dimensions, carrier-gas control, splitless injection mode, 250 °C inlet setting, and 1 µL injection are supported by the stated instrument configuration. However, the method requires an oven temperature of 320 °C, while the oven maximum is 300 °C. The column rating of 330 °C does not overcome the instrument'... | Use a GC with an oven rated for at least 320 °C, or revise the temperature program to remain at or below 300 °C and verify that the revised conditions provide acceptable separation. Confirm compatibility of the complete column and instrument configuration before operation. | Capillary GC method using a 30 m × 0.25 mm ID, 0.25 µm film column. Use helium at a constant flow of 1.2 mL/min, splitless injection at 250 °C, and an oven program ending at 320 °C with an 8-minute final hold. The column's stated maximum temperature is 330 °C. | The sample is a volatile organic mixture prepared in a GC-compatible solvent. Inject 1 µL using splitless mode; the sample preparation specifies no requirement for a heated transfer line. | Incompatible as written | Can the stated GC method, including its final oven temperature, be run on this instrument with the installed configuration? | The GC supports helium constant-flow control, splitless injection, and inlet temperatures up to 300 °C. The oven's maximum operating temperature is 300 °C. The installed capillary-column fittings accept columns with a 0.25 mm internal diameter. |
