GB/T 26792-2019High performance liquid chromatography (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 26792-2011 "High Performance Liquid Chromatograph".

Compared with GB/T 26792-2011, the main technical contents of this standard are as follows.

--- Revised the scope of non-applicability (see Chapter 1, Chapter 1 of the 2011 edition);

--- Added "good ventilation in the room" [see 3.1g)];

--- Revised the requirements for sealing indicators (see 3.3.1, 3.3.1 of the 2011 edition);

--- Modified Table 1 flow set value error and flow stability requirements, increased the flow rate of 5.0mL/min, 10.0mL/min Test points (see Table 1, Table 1 of the 2011 edition);

--- Modified the main technical indicators of the detector, and summarized the articles as shown in Table 2 (see Table 2, Table 3.5, 3.5 of the 2011 edition);

--- Added diode array detector indicators and test methods, evaporative light scattering detector indicators and test methods (see Table 2, 4.5.1) 4.5.4);

---Modified security requirements (see 3.7, 3.7 of the 2011 edition);

---Modified the column oven test procedure (see 4.4.1.2, 2011 edition of 4.4.1.2);

--- Modified the dynamic baseline noise and drift test of the refractive index detector (see 4.5.2.1, 4.5.2.1 of the 2011 edition);

--- Modified the solution for the minimum detection concentration of the refractive index detector (see 4.5.2.2, 2011 edition 4.5.2.2);

--- Modified the solution for the minimum detection concentration of the fluorescence detector (see 4.5.3.3, 2011 edition 4.5.3.3).
