The Model AS-1555 and AS-1555-10 are fully automatic sample injection systems enabling greater productivity and the highest possible level of precision. Sampling flexibility is unparalleled with up to 96 well positions (microplate) for laboratory automation and combinatorial chemistry. Also available is a rack for 84 micro-vials or the standard rack for 50 2 ml vials. The AS-1555/1555-10 offer 5 operating modes; normal, two methods of pre-column derivatization, dilution, and zero-sample loss injection in stand-alone mode. In the zero-sample loss mode, the sample is sandwiched between two zones of mobile phase solvent, and the entire sample volume is drawn into the loop and injected without loss.

The AS-1555 and AS-1555-10 can be easily combined with the HPLC system and the HSS-1500 software for Windows NT^®. The HSS-1500 program offers full automation of your HPLC system including the autosampler, along with an audit trail and enhanced GLP compliance. The software also allows display and document maintenance information of the detector, analysis log, SOP and results of instrument validation for laboratories in regulated industries.

Features

Excellent injection reproducibility
The AS-1555/1555-10 offer operation in both fixed loop or variable volume injection modes. The reproducibility achieved in fixed loop 20 Fl injection is less than 0.2% SD with less than 0.01% sample contamination. In variable 10 Fl injections SD was less than 0.3%.

Complete flexibility
Random sample access is provided as well as random number of injections and random injection volume for each vial. Urgent samples can be given priority.

Temperature control (AS-1555-10 only)
The AS-1555-10 offers a built-in Peltier cooling and heating unit to expand the versatility of the instrument and maintain the integrity of all samples.

Non-adsorbent tubing
The AS-1555/1555-10 both use an innovative stainless steel tubing, eliminating the adsorption problem than occurs when analyzing natural samples using Teflon tubing.

Sample pretreatment capability
Air segmented sampling enables the AS-1555 and AS-1555-10 to automatically mix up to two different solvents or derivatizing reagents with the sample in a stand-alone mode. By automating the processes of derivatizations, the sample pretreatment capability saves time and improves the precision of complex chromatographic analyses.

Interfacing with the HPLC system
The AS-1555/1555-10 can be used as stand-alone module through the built-in keypad and LCD display, or integrated into a complete HPLC system with computer control. In stand-alone mode, the advanced microprocessor of the AS-1555/1555-10 offer 10 user friendly programs with 64 steps per program. The AS-1555/1555-10 can freely interact with other HPLC modules via the built-in LC-Net interface and can also easily be triggered from an external event generated by a computer or other LC modules. Full PC control is also provided when incorporated in a HPLC system with our new 3 bit HSS-1500 HPLC System control software for Windows NT^®.

GLP/GMP compliance
The AS-1555/1555-10 were designed keeping GLP/GMP compliance in mind. Various GLP/GMP parameters including serial number, number of injections and number of suctions, are displayed in the LCD display. Utilizing the 32 bit HSS-1500 HPLC System control software, this GLP/GMP information is stored in a database along with an analysis log. Instrument validation can also be easily performed according to an electronic Standard Operation Procedure (SOP) provided with the HSS-1500 program. Test results of validation are recorded manually, and the results obtained are automatically compared with acceptable criteria set by user. The results can be printed for hard copy documentation along with the SOP. These various functions allow users to fully comply with GLP/GMP requirements.
