SECcurity column compartment 80°/100°
  SECcurity isocratic pumps  
Part number: 404-0001
Option seal wash: 404-0016 
This ideal GPC/SEC pump has the highest run-to-run and day-to-day precision of retention times. The optimized design ensures virtually pulse-free and stable solvent flow, with dual floating pistons in series, precisely servo-controlled. 
This delivery principle allows variable stroke volume optimized to selected flow rate. An inlet-valve electronically activated and synchronized to piston stroke - eliminates vapor formation with volatile solvent. Low operating and maintenance costs are due to long instrument uptime. Versatile wide flow range - up to 10 mL/min, includes semi-preparative separations. Robust materials withstand most demanding applications - stainless steel, titanium, gold, ruby, sapphire, ceramics, PEEK and PTFE ensure long lifetime. Seal wash option for high salt mobile phases keeps maintenance to a minimum for lower operation costs

Flow Specifications    
Precision:  ≤0.07 % RSD,or ≤0.02 min SD whatever is greater, based on retention time at constant room temperature
Accuracy:   ± 1 % or 10 µL/min whatever is greater
Range:  Setpoints from 0.001 to 10.0 mL/min, in 0.001 mL/min increments
Pressure Specifications 
Operating range:   0 - 40 MPa (0 - 400 bar, 0 - 5880 psi) up to 5 mL/min; 
0 - 20 MPa (0 - 200 bar, 0 - 2950 psi) up to 10 mL/min

Pulsation:   <2 % amplitude (typically <1 %) at 1 mL/min isopropanol at all pressures >1 MPa (> 10 bar, >147 psi)

Compress.compensation: User selectable, based on mobile phase compressibility
pH range:   1.0 - 12.5;  Solvents with pH <2.3 should not contain acids which attack steel
GLP/Compliance:  Electronic records of maintenance and errors. Early maintenance feedback (EMF) for continuous tracking of instrument usage, display of feedback messages if preset limits are exceeded.
 



SECcurity binary pump
  SECcurity binary pump
Part number: 404-0002
Option seal wash: 404-0024
The SECcurity binary pump is based on a high-pressure mixing principle. It is the pump of choice for reproducible gradients and high performance, especially at low flow rates and for high throughput applications. 
It has an optional programmable solvent selection valve which combines two out of four solvents for utmost flexibility and increased convenience, for example, when flushing the column. Reliable design keeps maintenance to a minimum using electronically-controlled active inlet-valves for flow rates up to 5.0 mL/min. The binary pump is also ideally suited to do standard-bore chromatography. Floating pistons with path-of-least-resistance principle ensures highest seal lifetime.

Flow Specifications    
Precision:  ≤0.07 % RSD,or ≤0.02 min SD whatever is greater, based on retention time at constant room temperature
Accuracy:   ± 1 % or 10 µL/min whatever is greater
Range:  Setpoints from 0.001 to 5.0 mL/min, in 0.001 mL/min increments
Pressure Specifications 
Operating range :   0 - 40 MPa (0 - 400 bar, 0 - 5880 psi) up to 5 mL/min; 
Pulsation:   <2 % amplitude (typically <1 %) at 1 mL/min isopropanol at all pressures >1 MPa (> 10 bar, >147 psi)
Compress. compensation: User selectable, based on mobile phase compressibility
Gradient Specifications
Delay volume:    180 - 480 µl (600-900 µl with mixer) dependent on back pressure
Composition precision:  <0.15 % RSD, 1 mL/min
Composition accuracy:  <0.5 % absolute
pH range:   1.0 - 12.5;  Solvents with pH <2.3 should not contain acids which attack steel
GLP/Compliance:  Electronic records of maintenance and errors. Early maintenance feedback (EMF) for continuous tracking of instrument usage, display of feedback messages if preset limits are exceeded.
 


SECcurity quaternary pump
  SECcurity quarternary pump
Part number: 409-0003
The SECcurity quaternary pump is for low pressure mixing of up to four solvents. The quaternary pump provides highest flexibility in solvent mixing and is recommended for a wide range of research and routine applications, and in the method development area.
It comes with an incorporated vacuum degasser that ensures virtually pulse-free and stable solvent flow, with dual floating pistons in series, precisely servo-controlled. The variable stroke volume allows pulse-free solvent delivery and efficient mixing. An inlet-valve electronically activated and synchronized to piston stroke - eliminates vapor formation with volatile solvents. Keeps maintenance and operation costs to a minimum, by use of  robust materials such as stainless steel, titanium, gold, ruby, sapphire, ceramics, PEEK and PTFE. Optional active seal wash option for high salt mobile phases to prevent corrosion. Wide flow range of up to 10 mL/min, including semi-preparative separations.

Flow Specifications    
Precision:  ≤0.07 % RSD,or ≤0.02 min SD whatever is greater, based on retention time at constant room temperature
Accuracy:   ± 1 % or 10 µL/min whatever is greater
Range:  Setpoints from 0.001 to 10.0 mL/min, in 0.001 mL/min increments
Pressure Specifications 
Operating range:   0 - 40 MPa (0 - 400 bar, 0 - 5880 psi) up to 5 mL/min; 0 - 20 MPa (0 - 200 bar, 0 - 2950 psi) up to 10 ml/min
Pulsation:   <2 % amplitude (typically <1 %) at 1 mL/min isopropanol at all pressures >1 MPa (> 10 bar, >147 psi)
Compress. compensation: User selectable, based on mobile phase compressibility
Gradient Specifications
Delay volume:    800 - 1100µL dependent on back pressure
Composition precision:  <0.20 % SD, at 0.2 and 1 mL/min
pH range:   1.0 - 12.5;  Solvents with pH <2.3 should not contain acids which attack steel
GLP/Compliance:  Electronic records of maintenance and errors. Early maintenance feedback (EMF) for continuous tracking of instrument usage, display of feedback messages if preset limits are exceeded.
